DTC P0335: Crankshaft Position (CKP) Sensor Circuit Malfunction (Esteem 1.8L)
- Turn ignition off. Disconnect PCM. Check PCM for good terminal contact at PCM connector E91 terminals No. 9 (White wire) and No. 19 (Black wire). If terminal contact is okay, measure resistance (backprobe) between PCM connector E91 terminal No. 9 (White wire) and No. 19 (Black wire). Resistance should be 484-656 ohms at 68°F (20°C). Measure resistance between each terminal and ground. One megohm or greater should be present. If resistances are to specification, go to step 3 . If resistances are not to specification, go to next step.
- Ensure ignition is off. Disconnect CKP sensor connector. Measure resistance between CKP sensor connector terminals No. 2 (Black wire) and No. 3 (White wire), then between each terminal and ground. If resistances are the same as those measured in previous step, check for open circuit in Black or White wire. If resistances are not the same as those measured in previous step, replace CKP sensor.
- Visually check CKP sensor and CKP sensor plate on crankshaft for damage or debris. Repair as necessary. If CKP sensor and CKP sensor plate are okay, check Black or Yellow wire for a short circuit. If wiring is okay, replace PCM.
