DTC P0335: CKP Sensor No Signal

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Start the engine.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 indicated?

YES -Go to step 5.

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the PCM.
Turn the ignition switch to LOCK (0).
Disconnect the CKP sensor 3P connector.
Turn the ignition switch to ON (II).
Measure the voltage between CKP sensor 3P connector terminal No. 1 and body ground.

Is there battery voltage?

YES -Go to step 9.

NO -Repair an open in the wire between the CKP sensor and PGM-FI main relay 1, then go to step 19.
Measure the voltage between CKP sensor 3P connector terminal No. 3 and body ground.

Is there battery voltage?

YES -Go to step 17.

NO -Repair an open in the wire between the CKP sensor and G101 (see CONNECTOR TO FUSE/RELAY BOX INDEX ), then go to step 19.
Turn the ignition switch to LOCK (0).
Jump the SCS line with the HDS.
Disconnect PCM connector C (49P).
Check for continuity between PCM connector terminal C32 and body ground.

Is there continuity?

YES -Repair a short in the wire between the PCM (C32) and the CKP sensor, then go to step 19.

NO -Go to step 15.
Connect CKP sensor 3P connector terminal No. 3 to body ground with a jumper wire.

Is there continuity?

YES -Go to step 25.

NO -Repair an open in the wire between the PCM (C32) and the CKP sensor, then go to step 19.
Turn the ignition switch to LOCK (0).
Replace the CKP sensor (see CKP SENSOR REPLACEMENT ).
Reconnect all connectors.
Turn the ignition switch to ON (II).
Reset the PCM with the HDS.
Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).
Do the CKP pattern clear/CKP pattern learn procedure (see CKP PATTERN CLEAR/CKP PATTERN LEARN ).
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 indicated?

YES -Check for poor connections or loose terminals at the CKP sensor and the PCM, then go to step 1.

NO -Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC'S TROUBLESHOOTING .
Reconnect all connectors.
Update the PCM if it does not have the latest software (see PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0335 indicated?

YES -Check for poor connections or loose terminals at the CKP sensor and the PCM, then go to step 1. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC'S TROUBLESHOOTING .

NO -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see PCM REPLACEMENT ). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC'S TROUBLESHOOTING .
