DTC P0335: CKP Sensor A Circuit Malfunction - M/T Model

1. Reset the ECM.
2. Start the engine.

Is DTC P0335, P0336, P0385, or P0386 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the CKP sensor A/B * and at the ECM.

3. Turn the ignition switch OFF.
4. Disconnect the CKP sensor A/B * 3P connector.
5. Turn the ignition switch ON (II).




6. Measure voltage between CKP sensor A/B * connector terminal No.3 and body ground.

Is there battery voltage?

YES - Go to step 7.

NO - Repair open in the wire between the ECM and CKP sensor A/B*.




7. Measure voltage between CKP sensor A/B * sensor 3P connector terminal No.1 (No.2 *) and body ground.

Is there about 5 V?

YES - Go to step 8.

NO - Go to step 10.




8. Measure voltage between CKP sensor A/B * 3P connector terminals No.3 and No.2 (No.1 *),

Is there battery voltage?

YES - Go to step 9.

NO - Repair open in the wire between the CKP sensor A/B * and G101.

9. Substitute a known-good CKP sensor A/B * and recheck.

Is DTC P0335, P0336, P0385, or P0386 indicated?

YES - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.

NO - Replace the original CKP sensor A/B *.




10. Measure voltage between ECM connector terminal A12 (A8 *) and body ground.

Is there about 5 V?

YES - Repair open in the wire between the ECM A12 (A8 *) and the CKP sensor A/B *.

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 A12 (A8 *) and body ground.

Is there continuity?

YES - Repair short in the wire between the ECM A12 (A8 *) and the CKP sensor A/B *.

NO - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.
