DTC P0335: CKP Sensor No Signal, DTC P0336: CKP Sensor Intermittent Interruption, DTC P0339: CKP Sensor Intermittent Interruption

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

Reset the ECM/PCM (see HOW TO RESET THE ECM/PCM ).
Start the engine.
Is DTC P0335 and/or P0336 (P0339)° 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 at the ECM/PCM.
Turn the ignition switch OFF.
Disconnect the CKP sensor 3P connector.
Turn the ignition switch ON (II).
Measure voltage between CKP sensor 3P connector terminal No. 3 and body ground.

Is there battery voltage?
1. YES - Go to step 7.
2. NO - Repair open in the wire between PGM-FI main relay 1 and the CKP sensor.
Measure voltage between CKP sensor 3P connector terminal No. 1 and body ground.

Is there about 5 V?
1. YES - Go to step 8.
2. NO - Go to step 10.
Measure voltage between CKP sensor 3P connector terminals No. 2 and No. 3.

Is there battery voltage?
1. YES - Go to step 9.
2. NO - Repair open in the BRN/YEL wire between the CKP sensor and G101.
Substitute a known-good CKP sensor and recheck.
Is DTC P0335 and/or P0336 (P0339)° indicated?
1. YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/ PCM, then recheck (see ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING ). If the symptom/ indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
2. NO - Replace the original CKP sensor (see CKP Sensor Replacement ).
Measure voltage between ECM/PCM connector terminal A7 and body ground.

Is there about 5 V?
1. YES - Repair open in the wire between the ECM/ PCM (A7) and the CKP sensor.
2. NO - Go to step 11.
Turn the ignition switch OFF.
Disconnect ECM/PCM connector A (31P).
Check for continuity between ECM/PCM connector terminal A7 and body ground.

Is there continuity?
1. YES - Repair short in the wire between the ECM/ PCM (A7) and the CKP sensor.
2. NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/ PCM, then recheck (see ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING ). If the symptom/ indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
