STEP 7. Check connector C-58 at ECM <M/T> or connector
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between camshaft position

sensor connector B-22 (terminal No. 5) and ECM
connector C-58 terminal 50 <M/T> or PCM connector
C-55 (terminal No. 56) <A/T> because of open circuit.
Then go to Step 19.

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

Connector Inspection

P.00E-2

. Then go to Step 19.

STEP 9. Check for short circuit to ground between
camshaft position sensor connector B-22 (terminal No. 5)
and ECM connector C-58 (terminal No. 50) <M/T> or PCM
connector C-55 (terminal No. 56) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 19.
NO : Repair it. Then go to Step 19.

STEP 10. Check the power supply voltage at camshaft
position sensor connector B-22.
(1) Disconnect the connector B-22 and measure at the harness

side.

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

(3) Measure the voltage between terminal No. 6 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage normal?

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

STEP 11. Check connector A-18X at MFI relay for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between MFI relay connector

A-18X (terminal No. 4) and camshaft position sensor
connector B-22 (terminal No. 6) because of open
circuit or short circuit to ground. Then go to Step 19.

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

Connector Inspection

P.00E-2

. Then go to Step 19.
