DTC P0335 - '01 Model: CKP Sensor Circuit No Signal, DTC P0336 - '01 Model: CKP Sensor Circuit Intermittent Interruption

Reset the PCM (see HOW TO RESET THE PCM ).
Start the engine.
Is DTC P0335 and/or P0336 indicated?
1. YES: Go to step 3.
2. NO: Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the PCM.
Turn the ignition switch OFF.
Disconnect the CKP sensor 2P connector.
Measure resistance between CKP sensor 2P connector terminals No. 1 and No. 2.

Is there 1,850-2,450 k ohms?
1. YES: Go to step 6.
2. NO: Replace the CKP sensor (see CKP Sensor Replacement ).
Check for continuity between body ground and CKP sensor 2P connector terminals No. 1 and No. 2 individually.

Is there continuity?
1. YES: Replace the CKP sensor (see CKP Sensor Replacement ).
2. NO: Go to step 7.
Reconnect the CKP sensor 2P connector.
Disconnect PCM connector A (31P).
Measure resistance between PCM connector terminals A12 and A24.

Is there 1,850 2,450 k ohms?
1. YES: Go to step 10.
2. NO: Repair open in the wire between the PCM (A12, A24) and the CKP sensor.
Check for continuity between body ground and PCM connector terminal A12.

Is there continuity?
1. YES: Repair short in the wire between the PCM (A12) and the CKP sensor.
2. NO: Substitute a known-good PCM and recheck (see HOW TO SUBSTITUTE THE PCM FOR TESTING PURPOSE ). If the symptom/indication goes away, replace the original PCM.
