[OBD-II] Oxygen Sensor Tests are OBD-II specific tests of each of the oxygen sensors on a vehicle. Although there are up to eight possible sensors the scanner can test, cer­tain vehicles may not support all eight tests, and most vehi­cles use only two or four. Oxygen Sensor Test values are divided in two types, a constant reading and a calculated reading. Constant readings are provided by the vehicle com­puter, calculated readings are determined from the sensor data.
Your vehicle must be scanned before viewing Oxygen Sensor Test data. If
MON is pressed, and the vehicle has not been scanned, the scanner will display

What to do When the Scanner Displays a Fault/Trouble Code
NOTE: AutoXray recommends obtaining a service manual or
repair manual to assist in automotive diagnostics. Manuals are available at your local parts store, book store, or library.
1. Check the connection to the sensor.
2. Look for obvious damage to any wires or vacuum hoses.
3. Locate a service or repair manual to look up the troubleshooting
tree for that fault code.
4. Follow the tree to determine the cause of the code.*
NOTE: Remember, the sensor itself is not always the cause of
the trouble code.
What to do for a "Vehicle Is Not Responding" Message
1. Make sure the vehicle ignition key is in the full ON position (not
ACC) and is making contact.
2. Make sure the diagnostic connector is clean.
3. Make sure the cable connectors are pushed in firmly.
4. Make sure the pins in the connectors are not bent and are
making contact.
5. Make sure the year and VIN are correctly entered.
6. Try wiggling the connector during the attempted scan.
Page 51
TROUBLESHOOTING
"Vehicle Is Not Responding" Message (continued)
Check the following “Manufacturer Specific” items:
[Ford] Make sure to connect both the multi-wire and the single-wire connectors to the AutoXray cable.
[Ford] At the beginning of a KOEO test, listen for solenoids clicking under the hood.
[Ford] Make sure the vehicle is fully warmed up before attempting the KOER test and give enough time to bring up "Scan Successful".
[GM] Answer any exception questions correctly.
[GM] On carbureted models, make sure the Check Engine Light is rapidly flashing during the attempted scan.
Screen Contrast Problems
Some users have experienced problems concerning screen contrast with newer batteries like the Duracell Ultra. These batteries produce a higher than normal voltage and can affect the scanner screen contrast, making the screen difficult to read. We apologize for the inconvenience. If you encounter this problem, run your scanner for approximately 2 hours to run off the high voltage causing the problem. (It will be necessary to press a key occasionally to override the EZ-SCAN scanner power miser function.)
NOTE: After these batteries reach their rated voltage (1.5V) the
battery life should still be approximately 500 hours.
How to Reset the Scanner
1. Power Scanner on.
2. Open the battery compartment and remove one battery.
3. Hold down POWER for 5 seconds.
4. Put the battery back in, and power on.

FORD DCL OPERATIONAL DATA ITEMS
Intake Air Temp (Volts) Range: 0 to 5 Volts
Displays the voltage of the temperature sensor which measures the temperature of the air flowing into the manifold.
Loop Status (Open/Closed)
If the loop status is OPEN, this means that the air/fuel mixture is being controlled by ECM tables or sensors other than the oxygen sensor. This is the case in a cold start condition, for example. When the engine coolant temperature sensor reaches a certain temperature (which depends on engine controller type) the loop status should transition to CLOSED. In closed loop, the air/fuel mixture is controlled by the oxygen sensor.
Low Speed Fan (On/Off)
The low speed fan is used in extreme conditions for transverse mounted engines. The screen should indicate ON if the ECM is commanding the low speed fan ON. If the ECM is commanding the fan OFF, the screen should indicate OFF.

The battery temperature sensor allows the ECM to monitor the ambient temperature of the battery.
Battery Temp (°F) Range: -40° to 260°
The temperature read from the converted battery temperature sensor input voltage.
Battery Voltage (Volts) Range: 0 to 16 Volts
This voltage is the charging system voltage while the engine is running, and the battery voltage when the engine is OFF.

The throttle body temperature sensor replaced the charge sensor on later models for vapor lock detection (see Throttle Body Temp).
Charge Temp Sens (Volts) Range: 0 to 5 Volts
The input voltage displayed is used by the PCM to convert to an actual temperature (see Charge Temp).
Closed Loop (Yes/No)
If Closed Loop is NO, this means that the air/fuel mixture is being controlled by PCM tables or sensors other than the oxygen sensor. This is the case in a cold start condition, for example. When the engine coolant temperature sensor reaches a certain temperature (which depends on engine controller type) the Closed Loop status should transition to YES. In closed loop, the air/fuel mixture is controlled by the oxygen sensor.
Cruise Input (Volts) Range: 0 to 1 Volt
The speed control system enabling input voltage, this parameter represents the switch state of the speed control system on vehicles equipped with speed control.

Amount of on-time base duration (pulse width) for an injector as determined by the PCM. The longer the duration, the more fuel being added. Pulse width will be less for Multi-port Fuel Injection (MFI) because there is an injector for every cylinder. Most Electronic Fuel Injection (EFI) and Throttle Body Injection (TBI) motors will have a longer duration due to there only being one or two fuel injectors.
Knock Sensor #x (Volts) Range: 0 to 5 Volts
The knock sensor is located in the intake manifold and will generate a signal to the PCM if knock is detected. This input is used by the PCM to retard the timing to eliminate the knock condition. The knock circuit is disabled at low RPM or in high manifold vacuum conditions. (x) refers to the bank of cylinders that the detonation sensor represents.
MAP Sensor (Volts / in-Hg) Range: 0 to 5 Volts, or 0 to 60 in-Hg
This sensor is used to monitor atmospheric (key on / engine running) and manifold absolute pressures in order to calculate manifold vacuum (engine load). This sensor along with others are used to modify the air/fuel mixture and spark advance. Higher voltages indicate higher engine load, where
Page 81
CHRYSLER OPERATIONAL DATA ITEMS
lower voltage represents a deceleration or cruise condition. The in-Hg value is determined by converting the MAP sensor input voltage to a pressure. The lower the MAP the higher the manifold vacuum.
Min Throttle Pos (Volts) Range: 0 to 5 Volts
This voltage is the idle TPS voltage which is used as a reference by the PCM. This voltage is the lowest TPS voltage, so that every movement of the throttle can be detected. This value is usually around 0.8 Volts.
Module Advance (°) Range: -10° to 70°
Base electrical spark advance as determined by the PCM. The PCM will use the coolant temperature sensor, engine speed, and vacuum to determine advance on a cold start. After the engine reaches normal operating temperature, the PCM will eliminate the coolant temperature sensor from the calculation.
O2 Bank x/ Pos y (Volts) Range: 0 to 1 Volts
The oxygen sensor generates an input voltage corresponding to the amount of oxygen in the exhaust. The oxygen sensor must reach a certain temperature before the readings are accurate. In closed loop (see Loop Status) the PCM will use this sensor for air/fuel mixture adjustments. This reading is the oxygen sensor reading for single oxygen sensor vehicles. For vehicles with multiple oxygen sensors, (x) refers to the first (or the only) bank of cylinders and (y) refers to either the pre- or post-catalytic position of the oxygen sensor. Pos 1 is the pre-catalytic position and Pos 2 is the post-catalytic position. A value of 0 to .5 Volts will indicate a lean mixture, a value of .5 to1.00 Volts will indicate a rich mixture.
O2 Bank x/ Pos y (State)

Throttle Body (° F) Range: -40° to 261°
The Throttle Body temperature indicates the fuel temperature in the throttle body of Single-Point fuel injected vehicles. This information is used to avoid vapor lock during hot restarts. The higher the tempera­ture, the wider the injector pulse width. This is known as the charge temperature on earlier model vehicles.
Throttle Open (% open) Range: 0 to 100%
The Throttle Open parameter is a relative percentage of throttle open­ing based on the learned minimum throttle position.
Throttle Posn (Volts) Range: 0 to 5 Volts
The voltage of the sensor mounted on the throttle shaft that relays throttle position back to the PCM. The throttle position helps determine the correct air/fuel mixture. At idle the TPS should read in the 0.5 to 1 volt range, at Wide Open Throttle (WOT) the TPS should read 4 -5 volts.
Total Spark Advance (° BTDC) Range: -10° to 70°
Total Spark Advance is the PCM base advance summed with specified mechanical advance.

total of 29 snapshots (Frames) of data in an entire capture. Depending on what capture “time” you choose, between 500ms
(1/2 sec.) to 5000ms (5 secs.), will be the wait time (interval) between each one of the snapshots (Frames).
For example, if you choose 1000ms (1 sec), intervals a frame would update data for a total of 29 frames of data, or 1 frame per second (29 sec. of elapsed time).
If you choose 500 ms (1/2 sec.) intervals a frame will update data for a total of 29 frames of data, or 1 frame per 1/2 second (14 1/2 sec. of elapsed time).
This is important to understand when viewing your captured data. Example: >>>>>>>T<, the < after the “T” represents the next frame of the captured data. When viewing this frame on the scan tool after a completed capture, the fame after the “T” is represented as “+A”. If 2000ms (2 sec.) was selected in capture time set up, “+A” would have occurred and been recorded 2 seconds after “T” and so on.

OBD-I
Original equipment automobile manufacturers (OEM) developed On-Board Diagnostics (OBD) in response to increased diagnostic requirements from the California Air Resource Board (CARB). The regulations that were developed by CARB and accepted by the Environmental Protection Agency (EPA) were designated OBD-I. Beginning in 1982 and by 1989 all new cars and light duty trucks sold in California had to have OBD-I.
OBD-I requires a Malfunction Indicator Lamp (MIL) or check engine light that illuminates to inform the vehicle operator when an emissions related component or a monitored system fails. The MIL dash indicator is usually amber or red in color. Each OEM manufacturer may call it by a different name.
The computer must have the capability to store Diagnostic Trouble Codes (DTCs). When a fault occurs, the MIL will illuminate and a DTC is stored in the computer's memory.
OBD-I requires monitoring of the Oxygen Sensor, EGR System, Fuel Delivery System, ECM or PCM, and Emission Related Electrical Components.
OBD-II
The California Air Resource Board (CARB) found that by the time an emission system component fails and causes the MIL to illuminate, the vehicle may have been emitting excess emissions for some time.
The OEMs had to develop new PCM self-diagnostic strategies in response to increased diagnostic requirements from the California Air Resource Board (CARB). The latest regulations developed by CARB and accepted by the Environmental Protection Agency (EPA) are designated OBD-II.
Page 89
TECHNICAL DESCRIPTION OF OBD-I, OBD-II AND CAN
The Federal Clean Air Act Amendments of 1990 requires that all vehicles sold in the United States meet OBD-II requirements by the 1996 model year. The first OBD-II systems appeared on selected vehicle types in 1994.
Some important OBD-II requirements are: Vehicle service information available to all technicians; Standardization of Terms: Use of SAE J-1930 recommended terms; OBD-II requires a common Diagnostic Link Connector (DLC) and specifies its location in the vehicle; Generic scan tool; Generic emission related Diagnostic Trouble Codes (DTC); and a very specific Malfunction Indicator Light (MIL) illumination protocol.
One very important part of the OBD-II requirements is that technical service information for emissions related components and systems, which could affect the vehicle's emission levels, will be available to all technicians; not just OEM dealership technicians. This will allow all technicians to better understand how the systems recognize faults and set the DTCs. The technician can now make a repair and verify the repair by exactly duplicating the criteria that is required for the DTC to be set.
What is CAN (Controller Area Network)?
CAN (Controller Area Network) is the newest computer protocol in the automotive industry. It is being rolled out in Ford, GM, Mazda and SAAB, current model year cars and is mandatory on all cars by
2008. Computerization of vehicles has shifted from one computer controlling everything to a distributed system consisting of many computers, each having its own area of responsibility. This raises the challenge of how to make all of the computers communicate with each other in order to share the work they do. The solution is CAN­the protocol that allows the manufacturers to implement fast, effi­cient, interoperable computers.
Page 90
TECHNICAL DESCRIPTION OF OBD-I, OBD-II AND CAN
CAN is a high-speed data link that runs fifty times faster than the pro­tocols currently implemented in today's vehicles. This speed, com­bined with the new parameters defined for CAN, will give technicians the ability to see data faster and gain a more accurate diagnosis.
In the past, protocols used by the car companies were proprietary. This ended in 1996 with the advent of OBD-II, which forced the man­ufacturers to select between 4 different types of communications: J1850-PWM, J1850-VPW, ISO-9141 and ISO-14230. Allowing four different protocols has created many complications in repair, inspec­tion and maintenance.
CAN was first established by Bosch as an industrial control network, but car companies soon found it was a very robust protocol for in­vehicle use. As early as 1992, Mercedes and others placed intricate CAN networks in their vehicles to handle communications between controllers.
The CAN protocol has been integrated into the OBD-II spec by the International Standards Organization (ISO) committee and has been accepted as the standard diagnostic protocol by manufacturers. In addition, the California Air Resources Board (CARB) has embraced CAN and made it mandatory for all vehicles. Manufacturers can begin implementing CAN in 2003 and must be CAN compliant by 2008 model year. The CAN standard is also a mandatory part of each new state emissions inspection and maintenance program and will be retrofitted into the established programs.
AutoXray's newest tool is CAN-ready and all AutoXray EZ-Link tools are software upgradeable to support CAN.
