Walker Engine Coolant Temperature Sensor With Pigtail 11-16 Ford 6.7L Powerstroke

Is your truck struggling with hard starts, erratic temperature readings, or poor fuel economy due to a failing coolant temp circuit? This Engine Coolant Temperature (ECT) Sensor with Pigtail restores accurate coolant data and fixes one of the most common failure points in the system, the wiring connection itself. The sensor feeds critical temperature information to the ECM so it can properly control fuel delivery, timing, and cooling strategy. When either the sensor or the connector starts to fail, you may notice drivability issues, overheating, or inconsistent gauge readings. Replacing both with this direct-fit solution restores reliable temperature feedback, smoother operation, and consistent engine performance, whether you're daily driving or towing heavy loads. Built for long-term reliability in harsh engine environments, this sensor is manufactured from high-quality, heat-resistant materials that withstand extreme temperature cycling, vibration, and constant exposure to coolant. The included pigtail harness features durable, corrosion-resistant wiring and sealed connectors to help prevent signal loss and eliminate intermittent electrical faults caused by worn or brittle factory plugs. The sensing element uses a precision thermistor that provides accurate resistance changes in response to coolant temperature for stable ECM communication. Fully engineered to OE specifications and tested for fit, form, and function, this kit provides a complete, dependable repair solution for lasting performance and reliability.
