P0335
DTC P0335: CKP Sensor No SignalNOTE:
- Information marked with an asterisk (*) applies to '01-03 models.
- Information marked with an asterisk (**) applies to '04 model.
1. Reset the ECM/PCM.
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/PCM.
3. Turn the ignition switch OFF.
4. Disconnect the CKP sensor 3P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between CKP sensor 3P connector terminal No. 3 and body ground.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between PGM-FI main relay 1 and the CKP sensor.
7. Measure voltage between CKP sensor 3P connector terminal No. 1 and body ground.
Is there about 5 V?
YES - Go to step 8.
NO - Go to step 10.
8. Measure voltage between CKP sensor 3P connector terminals No. 2 and No. 3.
Is there battery voltage?
YES - Go to step 9.
NO - Repair open in the wire between the CKP sensor and Q101.
9. Substitute a known-good CKP sensor and recheck.
Is DTC P0335 and/or P0336* (P0339)** indicated?
YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
NO - Replace the original CKP sensor.
10. Measure voltage between ECM/PCM connector terminal A7 and body ground.
Is there about 5 V?
YES - Repair open in the wire between the ECM/PCM (A7) and the CKP sensor.
NO - Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect ECM/PCM connector A (31P).
13. Check for continuity between ECM/PCM connector terminal A7 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM/PCM (A7) and the CKP sensor.
NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
