ON-VEHICLE INSPECTION

NOTICE:
In this section, the terms "cold" and "hot" refer to the
temperature of the coils. "Cold" means approximately ­10°C (14°F) to 50°C (122°F). "HOT" means approximately
50°C (122°F) to 100°C (212°F).

1. INSPECT IGNITION COIL ASSEMBLY

(a) Check for DTCs.

NOTICE:
If any DTC is present, perform troubleshooting
in accordance with the procedures for that DTC.

(b) Check that sparks occur.

(1) Remove the intake air surge tank (See page

FU-13).

(2) Remove the No. 1 surge tank stay (see page

IG-10).

(3) Disconnect the 6 ignition coil connectors and

remove the 6 bolts and 6 ignition coils.

(4) Using a 16 mm (0.63 in.) plug wrench, remove

the 6 spark plugs.

(5) Disconnect the 6 fuel injector connectors.
(6) Install the spark plugs to each ignition coil, and

connect the ignition coil connectors.

(7) Ground the spark plugs.
(8) Check if a spark occurs at each spark plug

while the engine is being cranked.

NOTICE:

• Be sure to ground the spark plugs when
checking.

• Replace the ignition coil if it receives an
impact.

• Do not crank the engine for more than 2

seconds.

(c) Perform the spark test according to the flowchart

below.
(1) Check that the ignition coil connector is

securely connected.

(2) Perform a speak test on each ignition coil.

1. Replace the ignition coil with a normal one.

2. Perform the spark test again.

(3) Check the power supply to the ignition coil.

1. Turn the ignition switch on (IG).

2. Check that there is battery voltage at the
ignition coil positive (+) terminal.

Result

Result Proceed to
NG Check wiring between ignition

switch and ignition coil

OK Go to next step

(4) Check the VVT sensor output voltage.

Result

Result Proceed to
NG Check that there is resistance

between ECM and VVT sensor. If
there is no resistance, replace VVT
sensor. If there is resistance, repair
wiring between VVT sensor and
ECM.

OK Go to next step

(5) Measure the resistance of the crankshaft

position sensor.

Standard resistance

Temperature Specified Condition
Cold 1,630 to 2,740 Ω
Hot 2,065 to 3,225 Ω
