The function of an automotive crankshaft position sensor is to monitor and detect the position and rotational speed of the crankshaft in the engine. It provides essential information to the engine control unit (ECU) or powertrain control module (PCM) to determine the precise timing for fuel injection and ignition system. This data helps the ECU/PCM in adjusting the air-fuel mixture and timing for optimized engine performance. Additionally, the crankshaft position sensor is also used for various other functions such as detecting misfires, controlling variable valve timing systems, and ensuring accurate synchronization of engine components.

The function of an automotive crankshaft position sensor is to monitor the rotational speed, position, and alignment of the crankshaft. It provides crucial information to the engine control unit (ECU) about the position of the crankshaft, which helps in determining ignition timing, fuel injection timing, and other engine parameters. By continuously measuring the crankshaft position and speed, the sensor helps ensure proper engine operation, optimal fuel efficiency, and accurate ignition timing for smooth engine performance.
