Walker Products 211-1071 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1071 Engine Coolant Temperature Sensor (ECT Sensor) is a direct-fit replacement designed to restore accurate coolant temperature monitoring to your vehicle's engine management system. The sensor continuously relays real-time coolant temperature data to the engine control module (ECM), which relies on this input to regulate fuel injection, ignition timing, cold start enrichment, and cooling fan operation.

A failing or inaccurate coolant temperature sensor can trigger a check engine light and lead to poor fuel economy, reduced engine power, rough idle, surging, or stalling. Replacing a worn sensor with this Walker Products unit restores proper ECM function and helps protect the engine from overheating or running rich.
