Crankshaft Position Sensor

Crankshaft Position Sensors monitor crankshaft position and rotational speed, providing critical data to the Engine Control Unit (ECU) for fuel injection and ignition timing. Typically located near the crankshaft or flywheel, these sensors utilize inductive, Hall-effect, or magnetoresistive technology to generate a digital signal. Signal output correlates directly with engine RPM and crankshaft degree of rotation, enabling precise combustion control. Modern sensors increasingly incorporate digital signaling for improved noise immunity and accuracy. Failure results in hard starting, misfires, or complete loss of engine operation.
