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
. Then go to Step 20.

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
. 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
. Then go to Step 20.
