P0335
DTC P0335: CKP Sensor No SignalDTC P0339: CKP Sensor Circuit Intermittent Interruption (2004 - 2005 models)
NOTE:
- Information marked with an asterisk (*) applies to 2000 - 2003 models.
- Information marked with double asterisk (**) applies to 2004 - 2005 models
- Before you troubleshoot, record all freeze data and review the general troubleshooting information.
1. Reset the ECM.
2. Start the engine.
Is DTC P0335 and/or P0336* (P0339)** indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and at the ECM.
3. Turn the ignition switch OFF.
4. Disconnect the CKP sensor 3P connector.
5. At the sensor side, measure resistance between CKP sensor 3P connector terminals No. 1 and No. 2.
Is there 1,850 - 2,450 Ohm?
YES - Go to step 6.
NO - Replace the CKP sensor.
6. At the sensor side, check for continuity between CKP sensor 3P connector terminal No. 1 and body ground and terminal No. 2 and body ground individually.
Is there continuity?
YES - Replace the CKP sensor.
NO - Go to step 7.
7. Reconnect the CKP sensor 3P connector.
8. Disconnect ECM connector C (31P), and measure resistance between the ECM connector terminals C8 and C9.
Is there 1,850 - 2,450 Ohm?
YES - Go to step 9.
NO - Repair open in the wire between the ECM (C8, C9)and the CKP sensor.
9. Check for continuity between ECM connector terminal C8 and body ground.
Is there continuity?
YES - Repair short in the wire between ECM terminal C8 and the CKP sensor.
NO - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.
