Mercedes-Benz M274 Crankshaft Position Sensor | C-Class E-Class CKP Spares

Description

Restore precise ignition timing, reliable engine starting, and smooth idling with this premium Mercedes-Benz M274 Crankshaft Position Sensor (CKP). Specifically sourced and verified for vehicles equipped with the M274 turbocharged 1.6L and 2.0L 4-cylinder petrol engines—commonly found in the C-Class (W205), E-Class (W213), and GLC (X253)—this critical engine management sensor is the definitive fix for “no-start” conditions and intermittent stalling.

The Crankshaft Position Sensor is the heartbeat of the M274 engine’s electronic control system. It monitors the rotational speed and exact position of the crankshaft, sending real-time data to the Engine Control Unit ($ECU$) to dictate fuel injection timing and spark plug firing. Because it is located near the flywheel/transmission bell housing, it is subjected to extreme thermal cycling and engine vibrations. A failing sensor often manifests as a “crank but no start” symptom, especially when the engine is hot, or causes the vehicle to suddenly cut out while driving. If the $ECU$ loses this signal, it cannot synchronize the combustion cycle, leading to the “Check Engine” light ($MIL$) and diagnostic trouble codes like $P0335$ or $P0336$. Replacing a faulty sensor ensures your engine fires instantly and maintains peak fuel efficiency.

Manufactured with high-quality electromagnetic coils and heat-resistant synthetic casings, this sensor is designed to maintain signal integrity even under high-load operating temperatures. It features a precision-molded connector to ensure a moisture-tight link to the vehicle’s main wiring harness. Trust TP German Auto Spares for fully verified, workshop-tested Mercedes-Benz engine sensors, electronic modules, and mechanical spares that keep your M274 engine running with German precision.
