Product Details
The Honda OEM Crankshaft Position Sensor is a genuine factory replacement designed for select Honda K20 and K24 engines, including the Honda Civic Si and Honda CR-V. This sensor plays a critical role in engine operation by monitoring crankshaft position and rotational speed, allowing the ECU to accurately control ignition timing and fuel injection.
Located near the crankshaft pulley, the crankshaft position sensor detects crankshaft rotation and sends essential timing information to the engine management system. Accurate sensor readings are necessary for proper engine starting, smooth operation, and consistent performance.
Over time, crankshaft position sensors can fail due to heat, vibration, electrical faults, or damaged wiring. A malfunctioning sensor may cause extended cranking, intermittent stalling, engine misfires, a no-start condition, or a check engine light.
Manufactured to Honda's original equipment specifications, this sensor provides dependable performance and factory-quality fitment. It is an excellent replacement during engine repairs, K-Series rebuilds, or compatible engine swaps.
