A crankshaft position sensor is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

In a typical engine the crankshaft position sensor is integrated into the engine block or cylinder head. The sensor produces a signal that is transmitted to the engine control unit (ECU). The ECU uses this signal to determine the position of the crankshaft and the engine speed. This information is used to control the ignition timing and the fuel injection.

If the crankshaft position sensor is not working properly it can cause the engine to not start. This is because the ECU needs the crankshaft position sensor signal to be able to correctly control the ignition timing and the fuel injection. If the crankshaft position sensor is not working the ECU will not be able to correctly control the engine and it will not start.

There are a few things that can cause the crankshaft position sensor to stop working. The most common cause is a problem with the wiring harness. The wiring harness can become damaged or frayed over time. This can cause the signal from the sensor to be interrupted or lost.

Another common cause of a crankshaft position sensor failure is a problem with the sensor itself. The sensor can become dirty or damaged and stop working. This can be caused by a build-up of oil or debris on the sensor.
