Possible Causes
NOTE: The listed causes may not be a complete list of all potential issues 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
Description
The crankshaft position sensor (NE signal) consists of a signal plate and detection coil. The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34 signals per engine revolution. The engine control module (ECM) detects the standard crankshaft angle based on these signals, and the actual crankshaft angle of engine speed through the NE signals.
How to Repair
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
- Engine light on (or service engine soon warning light)
- Lack/loss of power
