STEP 6. Measure the sensor supply voltage at PCM 
connector D-134 by backprobing.
(1) Do not disconnect the PCM connector D-134.
(2) Disconnect the camshaft position sensor connector B-10.
(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal No. 70 and ground 

by backprobing.

• Voltage should be between 4.8 and 5.2 volts.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?

YES : Go to Step 7.
NO :  Go to Step 8.

STEP 7. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between camshaft position 

sensor connector B-10 (terminal No. 2) and PCM 
connector D-134 (terminal No. 70) because of open 
circuit. Then go to Step 20.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

STEP 8. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 9.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 20.

STEP 9. Check for short circuit to ground between 
camshaft position sensor connector B-10 (terminal No. 2) 
and  PCM connector D-134 (terminal No. 70).
Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 20.
NO :  Repair it. Then go to Step 20.

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

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 3 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts) 

present?
YES : Go to Step 12.
NO :  Go to Step 11.

STEP 11. Check connector B-22X at MFI relay for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between MFI relay connector B-

22X (terminal No. 1) and camshaft position sensor 
connector B-10 (terminal No. 3) because of open 
circuit or short circuit to ground. Then go to Step 20.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 20.

STEP 12. Check the continuity at camshaft position sensor 
connector B-10.
(1) Disconnect the connector B-10 and measure at the harness 

side.

(2) Check for the continuity between terminal No. 1 and 

ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Go to Step 15.
NO :  Go to Step 13.

STEP 13. Check connectorD-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 14.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection
