DTC P0335: CKP Sensor No Signal

NOTE: Information marked with an asterisk (*) applies to '04 model.

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. 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 G101.

9. Substitute a known-good CKP sensor and recheck

Is DTC P0335 and/or P0336 (P0339)* indicated?

YES - Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM

NO - Replace the original CKP sensor




10. Measure voltage between ECM connector terminal A7 and body ground

Is there about 5 V?

YES - Repair open in the wire between the ECM (A7)and the CKP sensor

NO - Go to step 11.

11. Turn the ignition switch OFF.
12. Disconnect ECM connector A (31P)




13. Check for continuity between ECM connector terminal A7 and body ground

Is there continuity?

YES - Repair short in the wire between the ECM (A7) and the CKP sensor.

NO - Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM.
