P0336

DTC P0335: CKP Sensor Circuit No Signal
DTC P0336: CKP Sensor Circuit Intermittent Interruption

1. Reset the PCM.
2. Start the engine.

Is DTC P0335 and/or P0336 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the CKP sensor and the PCM.

3. Turn the ignition switch OFF.
4. Disconnect the CKP sensor 2P connector.




5. Measure resistance between the CKP sensor 2P connector terminals No.1 and No.2.

Is there 1,850 - 2,450 Ohms?

YES - Go to step 6.

NO - Replace the CKP sensor.




6. Check for continuity between body ground and CKP sensor 2P connector terminals No.1 and No.2 individually.

Is there continuity?

YES - Replace the CKP sensor.

NO - Go to step 7.

7. Reconnect the CKP sensor 2P connector.
8. Disconnect PCM connector A (31P).




9. Measure resistance between PCM connector terminals A12 and A24.

Is there 1,850 - 2,450 Ohms?

YES - Go to step 10.

NO - Repair open in the wire between the PCM (A12, A24) and the CKP sensor.




10. Check for continuity between body ground and PCM connector terminal A12.

Is there continuity?

YES - Repair short in the wire between the PCM (A12) and the CKP sensor.

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