Crankshaft Position Sensors

A crankshaft position sensor (often abbreviated as CPS or CKP sensor) is a critical component in modern internal combustion engines. Its primary function is to monitor the position and speed of the crankshaft, which is a vital parameter for the engine control unit (ECU) to determine ignition timing and fuel injection timing. Essentially, the crank sensor detects the rotational position of the crankshaft and sends this information to the ECU, allowing it to synchronize the ignition system and fuel injectors precisely. This synchronization is crucial for the engine to operate efficiently and smoothly.
