STEP 10. Measure the power supply voltage at crankshaft 
position sensor harness side connector B-119.
(1) Disconnect the connector B-119 and measure at the 

harness side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 1 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.

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)

STEP 14. Check harness connector B-10 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 15.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. 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 
− ID Code Registration Judgment Table <Vehicles

. Then go to Step 20.

NO :  Repair it. Then go to Step 20.

STEP 16. Check harness connector B-10 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 17.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. 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?

.

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.

.
