Crankshaft Position Sensor

Crankshaft Position Sensors, found within the Electrical & Lighting > Engine Electronics section, are vital components in modern vehicle engine management systems. These sensors accurately determine the position and rotational speed of the crankshaft, providing critical data to the engine control unit (ECU) for proper ignition timing, fuel injection, and emissions control. Typically located near the crankshaft or flywheel, these sensors utilize inductive, Hall effect, or magnetoresistive technology to generate an electrical signal. A failing crankshaft position sensor can cause difficult starting, engine misfires, poor fuel economy, or a complete no-start condition. Examples of crankshaft position sensors available include Bosch 0281002406, 0281006009, and 0281002662, catering to a wide range of passenger cars and commercial vehicles.
