SAFETY RULES

The following safety instructions are based on the B71.3 specifications of the American National Standards Institute in effect at the time of production.

Training

Read, understand and follow all instructions on the machine and in the manual(s) before operating this unit. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.
Never allow children to operate or play on or near the equipment. Never allow adults to operate the equipment without proper instruction.
Keep the area of operation clear of all persons, particularly small children. Be alert and shut off unit if children enter area.
Exercise caution to avoid slipping or falling, especially when operating the snow thrower in reverse.
Always remove key and/or wire from spark plug before assembly, maintenance or service. Unintentional engine start up can cause death or serious injury.
Complete a walk-around inspection of the unit to understand the unit, your work area and all safety decals.
Understand how to operate all controls, the functions of all controls and how to STOP in an emergency.

Preparation

Always check overhead and side clearances carefully before operation.
Always be aware of traffic when operating near streets or along curbs.
Thoroughly inspect the area where the equipment is to be used and remove all doormats, sleds, boards, toys, wires and other foreign objects.
Disengage all clutches and shift into neutral before starting the engine.
Use extension cords and receptacles as specified by the manufacturer for all units with electric drive motors or electric starting motors.
Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.
• Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle, before filling.
• When practical, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times, until refueling is complete. Do not use a nozzle lock-open device.
• Replace gasoline cap securely and wipe up spilled fuel.
• If fuel is spilled on clothing, change clothing immediately.
Adjust the auger / impeller housing height to clear gravel or crushed rock surface.
Never attempt to make any adjustments while the engine is running (except when specifically recommended by manufacturer).
Always allow unit and engine to adjust to outdoor temperature before clearing snow.

Operation

Disengage all controls before starting engine.
Never leave a running unit unattended. Always stop engine and remove key before leaving unit to prevent unauthorized use.
Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.
Moving and/or rotating parts can cut off body parts such as fingers or a hand. NEVER place your hands, other body part or clothing near any moving parts while unit is running.
Always keep hands away from all pinch points.
Do not touch parts which might be hot from operation. Allow parts to cool before attempting to maintain, adjust or service.
Thrown objects can cause injury. Check for weak spots on docks, ramps or floors. Avoid uneven work areas and rough terrain and stay alert for hidden hazards.
Exercise extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for hidden hazards or traffic.
EN – 5
After striking a foreign object, stop the engine, remove the wire from the spark plug, disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower.
If the unit should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.
Stop the engine whenever you leave the operating position, before unclogging the auger / impeller housing or discharge chute, and when making any repairs, adjustments or inspections.
When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the auger / impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent someone from accidentally starting the engine.
Do not run the engine indoors, except when starting the engine and for transporting the snow thrower in or out of the building. Open the outside doors; exhaust fumes are dangerous.
Never operate the snow thrower without proper guards, and other safety protective devices in place and working.
Always stand clear of the discharge area when operating this unit.
Never direct the discharge toward people or areas where injury or property damage can occur from thrown objects. Keep children and others away.
Do not overload the machine capacity by attempting to clear snow at too fast a rate.
Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when operating in reverse.
Do not operate in reverse unless absolutely necessary. Always back up slowly and look down and behind before and while backing.
Do not carry passengers.
Disengage attachment when not in use and when traveling from one work area to another.
Disengage power to the auger / impeller when snow thrower is transported or not in use.
Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counterweights or cabs).
This product is equipped with an internal combustion engine. Do not use unit on or near any unimproved, forest-covered or brush-covered land unless exhaust system is equipped with a spark arrester meeting applicable local, state or federal laws.

Hand contact with the rotating auger / impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute.
To clear the chute:

1. SHUT THE ENGINE OFF!

2. Wait 10 seconds to be sure the auger / impeller
blades have stopped rotating.

3. Always use a clean-out tool, not your hands.

Maintenance and Storage

Secure unit so it will not tip over during maintenance.
Before cleaning, removing clogs or making any inspections, repairs, etc., disengage clutch(es), stop engine, remove key, allow moving parts to stop and hot parts to cool.
Check shear bolts and other bolts at frequent intervals for proper tightness to be sure the equipment is in safe working condition.
Check clutch and brake operation frequently.
Do not change engine governor settings and do not over­speed engine.
Adjust and service as required. Motion of drive wheels and auger / impeller must stop quickly when clutch levers are released.
Always maintain unit in safe operating condition. Damaged or worn out muffler can cause fire or explosion.
Keep unit free of ice or other debris. Clean up oil or fuel spills.
Always keep protective structures, guards, and panels in good repair and secured in place. Never modify or remove safety devices.
Never store the machine with fuel in the fuel tank inside a building where ignition sources are present such as hot water heaters, space heaters or clothes dryers. Close fuel valve and allow the engine to cool completely before storing in any enclosure or covering the unit.
Always refer to operator's manual for important details if the snow thrower is to be stored for an extended period.
EN – 6
Maintain or replace safety and instruction labels as necessary.
Run the machine a few minutes after throwing snow to prevent freeze-up of the auger / impeller.

Personal Protection

Do not operate the equipment without wearing adequate winter garments. Avoid loose fitting clothing that can get caught in moving parts. Wear footwear that will improve footing on slippery surfaces.
Wear adequate safety gear, including safety glasses with side shields and protective gloves.
Do not wear loose clothing or jewelry, and tie back hair that may get caught in rotating parts.
NEVER attempt to unclog or clean unit while engine is running. Rotating auger / impeller can cause serious injury.
Protect eyes, face and head from objects that may be thrown from unit. Wear appropriate hearing protection.
Always wear safety glasses or eye shields during operation or while performing an adjustment or repair to protect eyes from foreign objects that may be thrown from the machine.

Slope Operation

Exercise extreme caution when operating on slopes. DO NOT operate on steep slopes. DO NOT clear snow across the face of slopes; go up and down. Keep all movement on slopes slow and gradual.
Use a slow speed to avoid stops or shifts on slopes. Avoid starting or stopping on a slope. Do not park unit on a slope unless absolutely necessary. When parking on a slope always block the wheels.
Do not operate near drop-offs, ditches, or embankments. Unit can suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.
When practical, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
If fuel is spilled on clothing, change clothing immediately.
Properly remove fuel before tipping unit up onto housing to avoid spills.

Towing/Transporting

Always stop engine, remove key and close fuel valve or drain fuel when transporting unit on a truck or trailer.
Use extra care when loading or unloading unit onto trailer or truck. Secure unit chassis to transport vehicle. Never secure from rods or linkages that could be damaged. Do not transport machine while engine is running.

Accessories

Use only AriensCo-recommended attachments or accessories that are designed for your unit and that are appropriate to your use and can be used safely in your application.

Fuel

DO NOT run engine in an enclosed area. Always provide good ventilation. Fumes from engine exhaust can cause injury or death.
Fuel is highly flammable and its vapors are explosive. Handle with care. Use only an approved gasoline container with an appropriately-sized dispensing spout.
No smoking, no sparks, no flames. Always allow engine to cool before servicing.
Never fill fuel tank when engine is running or hot from operation.
Never fill or drain fuel tank indoors.
Replace fuel cap securely and clean up spilled fuel.
Never fill fuel containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

The blinking red LED light on the ECU displays trouble codes. Its sequence indicates a particular system malfunction by blinking as many times as the first digit of a trouble code, pausing, and then blinking as many times as the second digit of a trouble code.
For example, the red LED will indicate low fuel pressure (27) by blinking twice, pausing, and blinking seven more times.
IMPORTANT: More than one trouble code may be present. IMPORTANT: DO NOT mistake a constant red (non-
blinking) LED for a trouble code. Red LED will illuminate when the ignition switch is turned to the “ON” position and the fuel pump is pressurizing, which may last for up to 30 seconds.
A blinking green LED indicates the ECU processor is operating correctly, even if a sub-component of the ECU (e.g.: barometric pressure sensor) has failed. A constant illuminated green (not blinking) LED indicates the ECU may be experiencing a low battery voltage condition or need
replacement. See EFI Trouble Code Identification on
page 73.
Visually inspect the red LED to verify trouble codes.
To read trouble codes more easily, place a mirror under the ECU to view LED reflection.
IMPORTANT: If no trouble code is present, but engine is not operating normally, See Diagnostics for Non-Tr ouble Codes on page 77.

MUST be 11.5 V AC – 14 V AC. If AC voltage measure less than 11.5 V AC, remove flywheel and replace stator.
If stator output is within range and battery is not charging, check ECU wiring for damage. Replace ECU if necessary.
a. With a multi-meter set to volts DC, back probe the
battery terminals. At full throttle (3600 RPM), the reading should be 7.5 V DC – 8.4 V DC.
b. Check the battery. With the engine off, the battery
voltage should be 7.2 V DC – 8.4 V DC. See Figure 177.
EN – 74

Code 21: Barometer Sensor

Figure 179

Temperature
Sensor
See Figure 170.
This trouble code indicates the barometric pressure sensor has failed. When the barometric sensor fails, the engine will not adjust to altitude changes, but will continue to operate at a default altitude of 800 feet above sea level.
Engine may continue to operate with a failed barometric pressure sensor, but may not operate at optimal performance. If barometric pressure sensor fails, replace ECU.

Code 22: Engine Temperature Sensor

See Figure 170.
If the sensor is damaged or has failed, the engine may not run smoothly because the ECU cannot adjust for engine temperature changes.
The temperature sensor and engine components can be visually inspected for engine temperature issues:

1. Check engine cooling fan and engine cooling fins for debris or damage.

2. Check the temperature sensor wiring from the throttle body to the mounting boss on the side of the cylinder. Make sure connection is secure. See Figure 179.

Code 23: EFI System Cannot Sustain Desired RPM

The ECU reads the RPM through the alternator. If a faulty connection exists, the ECU will not read the RPM correctly.

1. Start engine.

2. Check AC voltage of the alternator by back probing the wire harness connector at the engine. Voltage should read 11.5 V AC – 14 V AC. If voltage is within specification record the voltage and move to step 3.

a. If voltage is not to specification, inspect wires to
connectors. If wires are disconnected, repair or replace wire harness.
b. If connections are in good condition, disconnect
and reconnect wire harness and recheck voltage. Voltage should read 11.5 V AC – 14 V AC.
c. If low or no voltage exists, remove the flywheel
and inspect the alternator ground wire contact. If ground wire is corroded, repair alternator. If ground contact is in good condition, replace alternator.

3. Check voltage of the black and gray wires to the 14-pin connector at the ECU. Record the voltage here and compare to reading from step 2.

a. If voltage drop of 1 V AC or greater is observed,
inspect wire connections for a disconnected or corroded connection. If wires are disconnected or corroded, repair or replace wire harness.
b. If connections are in good condition, disconnect
and reconnect harness and recheck for voltage drop. Voltage should read 11.5 V AC – 14 V AC.
c. If voltage drop of 1.0 V AC or higher is still
present, replace wire harness(es).

4. If voltage is within specification and less than 1 VDC voltage drop from alternator to ECU, and trouble code still appears or the engine is still not performing optimally, replace ECU.

3. Check wiring and connection from the throttle body to the ECU for damage.
If no damage is visible, replace throttle body assembly.
EN – 75

Code 27: Low Fuel Pressure

Low fuel pressure is usually a result of an empty fuel tank, but could also be from a clogged fuel filter or faulty fuel pump.
Attempt engine start and check for trouble code re­occurrence after each of the following steps. Refer to Operator’s Manual for engine starting instructions.

1. Check fuel level and fill fuel tank completely if not already full.

2. Check fuel lines to ensure there are no leaks or kinks.

3. Check inline fuel filter for debris and blockage. See Figure 180.

CAUTION: AVOID INJURY. Fuel lines are
pressurized; wear safety glasses.
4. Check fuel pump wiring to ensure it is connected

correctly. See Figure 181.
See Figure 182.
5. Remove the fuel pump wires, turn ignition key to the ON position and measure the fuel pump voltage. Voltage output should measure 7.2 V DC – 8.4 V DC.
NOTICE: Disconnecting wires from fuel pump incorrectly
can cause damage to the fuel pump. To disconnect fuel pump wires, carefully compress the center tab of the connector and gently pull the connector away from the fuel pump.
IMPORTANT: Fuel pump voltage MUST be measured
within 30 seconds of the ignition switch being turned to the ON position. See Figure 183.
If voltage measures less than 7.2 V DC, check the battery voltage by probing the green wire on the ECU 12-pin connector. See Figure 184.
• If low voltage or no voltage is present, replace the ECU.
• If voltage is present, inspect the green wire between the 12-pin connector and throttle body for a pinched or broken wire. If the wire has no damage, replace the throttle body assembly.
• If voltage measures 7.2 V DC – 8.4 V DC, turn ignition key to OFF position, reconnect fuel pump wires and turn key back to ON position. Fuel pump should make a “humming” noise.
If fuel pump is silent, the pump may have failed. Check fuel pump:
1. Drain fuel from fuel system and tank. See Draining Fuel System on page 7.
EN – 76
2. Remove pump from tank.
Yellow

3. Reconnect pump wires.
4. Turn the ignition key to the ON position and listen for a “humming” noise.
If fuel pump is silent, replace fuel pump.
If voltage is within range and fuel pump is operating normally, the fuel pressure sensor is defective. Replace the throttle body assembly. See Figure 189.

Code 28: High Battery Voltage

This trouble code will activate if ECU detects a higher voltage from the stator.

1. Start the engine. Refer to Operator’s Manual.

2. Set a multi-meter to V AC and probe the red and black stator connector wire. The output should be
11.5 V AC – 14 V AC at full throttle (3600 RPM).
If stator output measures over 14 V AC, replace stator. If output is within range, advance to step 3. See Figure 178.
IMPORTANT: If the engine is cold, it is normal for the
engine speed to be 100 RPM – 200 RPM higher until operating temperature is reached.

3. Set a multi-meter to V DC and probe the battery connector at the battery terminals. With the engine running at full throttle (3600 RPM), the output should be 7.2 V DC – 8.4 V DC.

If DC output is higher than 8.4 V DC, replace ECU. See Figure 177.
If DC output is within range and red trouble code persists, replace ECU.

DIAGNOSTICS FOR NON-TROUBLE CODES

IMPORTANT: The following conditions and diagnostic
procedures apply to EFI components only.

Engine Starts and Loses Power

If the engine starts and loses power immediately, this is usually an indication that the ECU does not detect an RPM signal. The RPM signal is generated by the stator, which also powers the hand warmers, headlight and charges the ECU battery.
Common causes for RPM signal failure may be due to a disconnected engine wire harness or a ground short in the AC output wire from the stator to the ECU. Other possible causes may include an ECU or engine-charging system failure.

1. Check wire harness connection to the ECU.

a. With the ignition key in the off position, check the
wire harness connections to the ECU. If connections are secure, disconnect the 12-pin and 14-pin connections to the ECU and inspect connectors for bad connections or burn marks.
b. Check that all wire terminals are snug in their
connectors. If connections appear to be good, reconnect wire harness and start engine to check if issue is still present. If bad connection is present, replace wire harness.
c. If issue is still present, advance to next step.

2. Check the ECU.

a. Disconnect wire harness from ECU and test with a
new ECU to verify the original ECU is not cause for malfunction. If malfunction is not resolved with a new ECU, reconnect wire harness to original ECU and continue diagnostics.

3. Back probe the engine stator output connector. See Figure 178.

a. Start the engine. Refer to Operator’s Manual. b. At full throttle (3600 RPM), the stator output
MUST be 11.5 V AC – 14 V AC. If AC voltage measures less than 11.5 V AC, remove flywheel and replace stator.

Engine No-Start Condition

If the engine does not start, check for system power.

1. Check EFI battery fuse.

2. Check spark plug.

a. Stop engine, remove key and wait for all moving
parts to stop and for hot parts to cool.
b. Disconnect the spark plug wire and remove debris
from the spark plug area.
c. Remove spark plug. d. Inspect the spark plug. Spark plug gap MUST be
0.7 mm – 0.8 mm (0.027" – 0.030"). Replace if the
electrodes are worn, fouled, or if the insulator is
cracked or chipped.
e. Position spark plug against engine block and pull
EN – 77
recoil starter handle to check for spark. If no spark

Gray Slide
is present, replace spark plug.
f. Reinstall spark plug and finger tighten. Turn an
additional 1/4 turn after spark plug is seated.
g. Reinstall spark plug wire and make sure it is
correctly positioned onto the spark plug.
3. Check the battery. Battery should have 7.2 V DC – 8.4 V DC, depending on when the battery was most recently charged. Extremely low voltage could prevent the ECU from triggering a trouble code and result in a no-start condition. If battery has low voltage, connect battery charger to battery. Also check the inline fuse on the battery cable.
If battery measures below specification after charging, replace battery.

4. Check wire harness connection to the ECU.

a. With the ignition key in the off position, check the
wire harness connections to the ECU. If connections are secure, disconnect the 12-pin and 14-pin connections to the ECU and inspect connectors for bad connections or burn marks.
b. Check that all wire terminals are snug in their
connectors. If connections appear to be good, reconnect wire harness and start engine to check if issue is still present. If bad connection is present, replace wire harness.
c. If issue is still present, advance to next step.

5. Check the ECU.

a. Disconnect wire harness from ECU and test with a
new ECU to verify the original ECU is not cause for malfunction. If malfunction is not resolved with a new ECU, reconnect wire harness to original ECU and continue diagnostics.
6. Check the ECU status. With battery voltage between
7.2 V DC – 8.4 V DC, check if the green ECU status light is blinking at a consistent rate.
IMPORTANT:
If battery measures below 7.2 V DC, ECU LEDs may appear dim or will not illuminate red or green LEDs.
If green LED is constant, (not-blinking)
see EFI Trouble Code Identification on page 73.

7. Check fuel pump output.

a. Remove the heater box.
b. Check voltage at fuel pump. See Code 27: Low
Fuel Pressure on page 75 for voltage readings.
c. Remove fuel hose from fuel pump outlet and
attach a suitable length of fuel hose to the fuel pump outlet that can safely reach a clearly marked fuel container.
d. With battery voltage between 7.2 V DC – 8.4 V
DC, turn the key to the ON position for 10 seconds to pump fuel into the container. Fuel should
measure approximately 160 mL (5 oz.). If fuel amount measures less than 160 mL, remove the fuel pump and check the pre-filter for blockage. If filter is clean, replace fuel pump. See Figure 185.
IMPORTANT: If replacing fuel pump, wet the fuel system:
a. Fill fuel tank full. b. Cycle ignition key to the ON position, then to the
OFF position. Repeat.
IMPORTANT: Cycling the ignition key multiple times may
inject excessive amounts of fuel into the throttle body and “flood” the engine. A flooded engine may require more starting attempts than normal.
8. Remove connector to the injector.
a. Move gray slide upward until it stops. Gently
compress gray slide and remove connector. See Figure 186.
b. Set a multi-meter to V DC and probe each
terminal with the red probe and contact the black probe against the engine block. With the ignition key in the ON position, each terminal should measure 7.2 V DC – 8.4 V DC. See Figure 187.
EN – 78
If voltage is within range and the fuel injector is not

Figure 187

Figure 188

operating correctly with the key in the ON position, replace throttle body assembly.
c. If no voltage is present at the injector, check
battery voltage by probing the red and white wires
on the
12-pin ECU connector with the red probe and
contact the black probe against the engine block.
With the ignition key in the ON position, each
terminal should measure 7.2 V DC – 8.4 V DC.
See Figure 188.
EN – 79
If no voltage is present at the ECU, replace ECU. If voltage

Figure 189

Figure 190

is present at the ECU, check wires for kinks or damage. If damage is present repair wires if possible, or replace throttle body. See Figure 189.

Surging Run Condition

1. Check wire harness connection to the ECU.

a. With the ignition key in the off position, check the
wire harness connections to the ECU. If
connections are secure, disconnect the 12-pin
and 14-pin connections to the ECU and inspect
connectors for bad connections or burn marks.
b. Check that all wire terminals are snug in their
connectors. If connections appear to be good,
reconnect wire harness and start engine to check
if issue is still present. If bad connection is
present, replace wire harness.
c. If issue is still present, advance to next step.

2. Check the ECU.

a. Disconnect wire harness from ECU and test with a
new ECU to verify the original ECU is not cause
for malfunction. If malfunction is not resolved with
a new ECU, reconnect wire harness to original
ECU and continue diagnostics. If the AC output wire from the engine charging system is
damaged, it may cause an intermittent short. This will result in erratic running such as the engine over revving or “popping” through the exhaust.
3. Check the engine wiring and wiring under the
handlebar to verify that it is not damaged.

4. With an inline spark tester, check ignition for intermittent spark.

5. Check fuel pump output.

a. Remove the heater box.
b. Check voltage at fuel pump. See Code 27: Low
Fuel Pressure on page 75 for voltage readings.
c. Remove fuel hose from fuel pump outlet and
attach a suitable length of fuel hose to the fuel pump outlet that can safely reach a clearly marked fuel container.
d. With battery voltage between 7.2 V DC – 8.4 V
DC, turn the key to the ON position for 10 seconds to pump fuel into the container. Fuel should
measure approximately 160 mL (5 oz.). If fuel amount measures less than 160 mL, remove the fuel pump and check the pre-filter for blockage. If filter is clean, replace fuel pump. See Figure 185. If fuel pump output is to specification, replace the ignition coil.

Engine Speed Does Not Change

If engine speed does not change when using the potentiometer (throttle control), check the following:
1. Set a multi-meter to ohms () and measure the
potentiometer resistance. See Figure 190 and Figure 191.
a. Unplug the 14-pin connector from the ECU. b. Position the red probe on the terminal of the red
wire at the potentiometer (Pin 5 in Figure 190) and
the black probe on the terminal of the
green / white wire. The potentiometer output should measure 0 – 5000 Ω.
If ohm reading measures close to 0 at full throttle and close to 5000 at low-idle, potentiometer is operating normally. If ohm reading stays constant at either position, replace potentiometer.
2. With a multi-meter, measure the V DC of the red wire.
a. With engine off, reconnect the 14-pin connector to
the ECU.
b. Position the red probe on the terminal of the red
wire at the potentiometer (Pin 5 in Figure 190).
Also see Figure 191.
EN – 80
c. Position the black probe on the engine block.

Figure 191

Figure 192

d. Turn ignition key to ON position.
e. Turn the potentiometer from low-idle to full throttle. Voltage to the red wire should measure 4.90 V DC – 5.0 V DC at both low-idle and full throttle positions.
If voltage measures less than 4.9 V DC, replace ECU.
3. With a multi-meter, measure the V DC of the
green / white wire. See Figure 192.
a. With engine off, position the red probe on the
terminal of the green / white wire. b. Position the black probe on the engine block. c. Turn ignition key to ON position. d. Turn the potentiometer from low-idle to full throttle.
Voltage to the green / white wire should measure close to
0.01 V DC at low-idle and close to 5.0 V DC at full throttle.
If voltage does not vary between low-idle and full throttle, replace the ECU. If voltage varies at both terminals, replace throttle body.

Fluttering Servo Motor

If the throttle plate in the throttle body flutters continuously when the key is in the ON position, check the following:

1. Wire harness connection to the ECU.

a. With the ignition key in the off position, disconnect
the wire harness from the ECU and inspect connection at the tan, purple and yellow wires on the 12-pin connector. See Figure 184. If connection is faulty, repair, if possible. If repair cannot be completed, replace the throttle body.
b. If connection is good, a faulty connection exists in
the throttle body or servo motor. Replace the throttle body.
