DTC P0335: CKP Sensor No Signal

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review 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 ECM/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 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 about 5 V?

YES: Go to step 10.

NO: Go to step 11.

Measure the voltage between CKP sensor 3P connector terminals No. 1 and No. 2.
Is there battery voltage?

YES: Go to step 17.

NO: Repair open in the wire between the CKP sensor and G101; M/T model (see CONNECTOR TO FUSE/RELAY BOX INDEX ), A/T model (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 ECM/PCM connector C (49P).
Check for continuity between ECM/PCM connector terminal C32 and body ground.
Is there continuity?

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

NO: Go to step 15.

Check for continuity between ECM/PCM connector terminal C32 and body ground.
Is there continuity?

YES: Go to step 26.

NO: Repair open in the wire between the ECM/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 ECM/PCM with the HDS.
Clear the crank pattern with the HDS.
Do ECM/PCM IDLE LEARN PROCEDURE .
Do 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 ECM/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 ECM/PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/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 ECM/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 ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
