003 153 28 28 – Mercedes-Benz Crankshaft Position Sensor
Description
003 153 28 28 – Mercedes-Benz Crankshaft Position Sensor (Part Number: 003 153 28 28)
This electronic sensor is a critical component of the engine management system that monitors the rotational speed and exact position of the crankshaft. It sends high-frequency signals to the Engine Control Unit (ECU) to synchronize fuel injection and ignition spark timing. This specific ‘single-clip’ version uses the Hall Effect principle and is typically mounted on the engine bell housing to read a trigger wheel on the flywheel. A failing sensor often causes intermittent stalling, ‘no-start’ conditions when the engine is hot and stored diagnostic trouble codes (DTCs) related to engine timing.
