What does a crankshaft position sensor do?

The crankshaft position sensor plays a crucial role in your engine’s operation by monitoring the exact position and speed of the crankshaft as it rotates. This information is sent to the engine control unit (ECU), which uses it to determine the precise timing for fuel injection and ignition. Accurate crankshaft timing ensures that the pistons fire at the right moment, synchronizing with the camshaft and other engine components. If the sensor fails, the ECU can’t properly manage these timings, leading to misfires, rough idling, or even the engine failing to start. Replacing a faulty crankshaft position sensor restores proper timing and ensures your car runs smoothly.
