STEP 7. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Repair harness wire between camshaft position
sensor connector B-09 terminal 2 and ECM connector
C-60 terminal 88 <M/T> or PCM connector C-54
terminal 56 <A/T> because of open circuit. Then go to
Step 18.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection (
STEP 8. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 9.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 9. Check for short circuit to ground between
camshaft position sensor connector B-09 terminal 2 and
ECM connector C-60 terminal 88 <M/T> or PCM connector
C-54 terminal 56 <A/T>.
Q: Is the harness wire in good condition?
YES : Replace the ECM or PCM. Then go to Step 18.
NO : Repair it. Then go to Step 18.
STEP 10. Check the power supply voltage at camshaft
position sensor connector B-09.
(1) Disconnect the connector B-09 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 3 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-21X at MFI relay for damage.
Q: Is the connector in good condition?
YES : Repair harness wire between MFI relay connector A-
21X terminal 1 and camshaft position sensor
connector B-09 terminal 3 because of open circuit or
short circuit to ground. Then go to Step 18.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 12. Check the continuity at camshaft position sensor
connector B-09.
(1) Disconnect the connector B-09 and measure at the harness
side.
(2) Check for the continuity between terminal 1 and ground.
•
Should be less than 2 ohm.
Q: Is the continuity normal?
YES : Go to Step 13.
NO : Repair harness wire between camshaft position
sensor connector B-09 terminal 1 and ground
because of open circuit or harness damage. Then go
to Step 18.
STEP 13. Check connector A-21X at the MFI relay 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 (
STEP 14. Check connector C-60 at ECM <M/T> or
connector C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 15.
NO : Repair or replace it. Refer to GROUP 00E, Harness
