Walker 211-2114 Engine Coolant Temperature Sensor - Engine Block

Engine Coolant Temperature Sensor for BMW

Walker 211-2114 is a sensor-only engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. With accurate temperature input, the engine management system can adjust fuel injection, ignition timing, cold start enrichment, and cooling fan operation for consistent drivability.

This Walker Sensor Only line focuses on direct-fit replacement sensors engineered to match OE resistance values, thermal response, and signal output. The result is a practical replacement for BMW models that need dependable coolant temperature feedback, including BMW 330e, M240i, M340i, M440i, X1, X3, X4, and X7 applications.
