Code P1335 – Crankshaft Position Sensor
Possible Causes
NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.
- Faulty crankshaft position sensor
- Crankshaft position sensor (CKP) harness is open or shorted
- Poor electrical connection in crankshaft position sensor (CKP) circuit
- Signal plate may be damaged
- Starter may be faulty
- Starting system circuit
- Dead or weak battery
Description
The crankshaft position sensor (CKP), also known as the crankshaft position sensor, is an electronic device used in an engine to record the speed at which the crankshaft rotates. This information is used by the engine control module (ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disk, as well as a static part, the sensor itself.
When the engine rotates, the high and low parts of the teeth cause a change in the gap with the sensor. The changing gap results in a modification of the magnetic field near the sensor. The change in the magnetic field causes a variation in the sensor voltage.
