STEP 12. Check for open circuit and short circuit to
ground between crankshaft position sensor connector
B-119 (terminal No. 1) and ECM connector B-10 (terminal
No. 9).
Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles

with KOS>

. Then go to Step 20.

NO : Repair it. Then go to Step 20.

STEP 13. Check the continuity at crankshaft position
sensor harness side connector B-119.
(1) Disconnect the connector B-119 and measure at the

harness side.

(2) Check for the continuity between terminal No. 2 and

ground.

• Continuity (2 ohms or less)

Q: Does continuity exist?

YES : Go to Step 16.
NO : Go to Step 14.

. Then go to Step 20.

STEP 15. Check for open circuit and harness damage
between crankshaft position sensor connector B-119
(terminal No. 2) and ECM connector B-10 (terminal No. 24).
Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis

. Then go to Step 20.

STEP 17. Check for harness damage between ECM
connector B-10 (terminal No. 9) and crankshaft position
sensor connector B-119 (terminal No. 1).
Q: Is the harness wire in good condition?

YES : Go to Step 18.
NO : Repair it. Then go to Step 20.

STEP 18. Check for harness damage between crankshaft
position sensor connector B-119 (terminal No. 3) and ECM
connector B-10 (terminal No. 8).
Q: Is the harness wire in good condition?

YES : Go to Step 19.
NO : Repair it. Then go to Step 20.

STEP 19. Check the crankshaft position sensing ring.
Q: Is the crankshaft position sensing ring in good

condition?
YES : Replace the crankshaft position sensor. Then go to

Step 20.

NO : Replace the crankshaft sensing ring. Then go to Step

20.

STEP 20. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle − Pattern 23

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0335 set?

YES : Retry the troubleshooting.
NO : The inspection is complete.

.

CIRCUIT OPERATION

• The intake camshaft position sensor power is

supplied from the ECM (terminal No. 9).

• Terminal No. 2 of the intake camshaft position

sensor is grounded with ECM (terminal No. 30).

• A 5-volt voltage is applied on the intake camshaft

position sensor output terminal (terminal No. 3)
from the ECM (terminal No. 14). The intake cam-
shaft position sensor generates a pulse signal
when the output terminal is opened and
grounded.

.

TECHNICAL DESCRIPTION

• The intake camshaft position sensor detects the

position of the intake camshaft and inputs the
pulse signal to the ECM.

• In response to the intake camshaft position sen-

sor signal and the crankshaft sensor signal, the
ECM detects the compression top dead center of
the No. 1 cylinder.

• Also, in response to the intake camshaft position

sensor signal, the ECM controls variable valve
timing (V.V.T.).

.

DESCRIPTIONS OF MONITOR METHODS

• Intake camshaft position sensor signal does not

change.

• Intake camshaft position sensor signal is not nor-

mal pattern.

.
