Sensor Crank 3Pin (M272 OM642) (Mercedes-Benz C-Class W203 / W204 / E-Class W211 / M-Class W164 / SLK-Class R171 / SL-Class R230) is a crankshaft position sensor designed for specific Mercedes-Benz models across the C-Class, E-Class, M-Class, SLK-Class, and SL-Class ranges. This sensor plays a crucial role in monitoring the crankshaft’s position and rotational speed, information vital for engine management systems to control fuel injection and ignition timing.
This sensor is tailored for vehicles equipped with the M272 and OM642 engines, fitting multiple Mercedes-Benz chassis codes including W203, W204, W211, W164, R171, and R230. When sourcing a replacement, ensure the part matches these specific model and engine designations, as the 3-pin connector layout and sensor functionality are particular to these applications.
Replacing the crankshaft sensor can address symptoms related to engine timing errors or starting issues, but buyers should confirm compatibility by comparing the old sensor’s design, pin configuration, and engine code. The listing does not cover sensor coding, calibration, or fault diagnosis, so professional assessment is recommended if sensor-related electronic faults persist.
