P1361

DTC P1361: CMP (TDC) Sensor A Intermittent Interruption

NOTE: Information marked with an asterisk (*) applies to DTC P1366 or DTC P1367.

1. Reset the ECM.
2. Start the engine.

Is DTC P1361, P1362, P1366 and/or P1367 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at CMP (TDC) sensor A, CMP (TDC) sensor B* and at the ECM.

3. Turn the ignition switch OFF.
4. Disconnect the CMP (TDC) sensor A and CMP (TDC) sensor B* 2P connectors.




5. Measure resistance between CMP (TDC) sensor 2P connector terminals No.1 and No. 2.

Is there 1,850 - 2,450 ohms?

YES - Go to step 6.

NO - Replace the CMP (TDC) sensor A and/or CMP (TDC) sensor B*.




6. Check for continuity to body ground on all terminals individually.

Is there continuity?

YES - Replace the CMP (TDC) sensor A and/or CMP (TDC) sensor B*.

NO - Go to step 7.

7. Reconnect CMP (TDC) sensor A and CMP (TDC) sensor B* 2P connectors.
8. Disconnect ECM connector C (31P).




9. Measure resistance between ECM connector terminals C20 and C21 (C29 and C30)*.

Is there 1,850 - 2,450 ohms?

YES - Go to step 10.

NO - Repair open or short in the faulty sensor wire(s).




10. Check for continuity between body ground and ECM connector terminal C20 (C29) *.

Is there continuity?

YES - Repair short to body ground in the faulty sensor wire(s).

NO - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.
