A crankshaft position sensor reports crankshaft position and speed to the engine control module, which uses that signal to help time ignition and fuel injection. If the signal drops out or becomes erratic, the engine may run poorly or fail to start.
Signs this sensor may need replacing include an engine that cranks but will not start, stalling, hesitation or misfiring, and an illuminated check engine light. These symptoms can have other causes, so diagnose the problem before replacing parts. If a failed crankshaft position sensor is the cause, PC980 replaces it. Consult the vehicle service information for the sensor's location and the correct installation procedure.
