Code Definition
- DTC P0335: Crankshaft Position (CKP) Sensor "A" Circuit Malfunction
- DTC P1335: CKP Sensor Circuit Malfunction (While Engine Running)
| CAUTION | If ECM replacement is instructed in following testing, always ensure ECM harness connector and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction. If ECM is replaced, ECM must be programmed with proper ignition key code for engine immobilizer system. For programming procedures, see COMPUTER RELEARN PROCEDURES - IMPORT article in GENERAL INFORMATION. |
Circuit Description
Crankshaft Position (CKP) sensor consists of a pick-up coil and signal plate. Signal plate has 34-teeth and is located on crankshaft timing pulley. Pick-up coil is mounted on oil pump body. DTC P0335 is set if no signal is received by ECM from CKP sensor while engine is cranking. DTC P0335 is also set if no signal is received by ECM from CKP sensor with engine speed of 600 RPM of more. DTC P1335 is set if no engine running signal is received by ECM from CKP sensor with engine speed of 1000 RPM or more. Possible causes are
- CKP sensor open or short circuit.
- Faulty CKP sensor.
- Faulty crankshaft timing pulley.
- Faulty ECM.
Diagnostic Aids
Using scan tool, read freeze frame data. Freeze frame records engine conditions when malfunction is detected.
