Crankshaft Position Sensor

Crankshaft Position Sensors monitor crankshaft position and rotational speed to provide critical data for engine timing and fuel injection. Typically mounted near the crankshaft or flywheel, these sensors utilize a magnetic or Hall-effect principle to generate a digital signal proportional to rotational movement. Output signals are sent to the Engine Control Unit (ECU), enabling precise ignition and fuel delivery. Sensor construction commonly includes a shielded pickup element and robust housing for durability in harsh engine environments. Failure manifests as hard starting, rough running, or complete engine stall.
