Is your truck hesitating, lacking throttle response, or acting unpredictably when you press the pedal? The Walker Throttle Position (TPS) Sensor restores the precise throttle input signal your engine needs to perform correctly. This sensor monitors throttle position and sends that data to your ECM, which can adjust fuel delivery, timing, and transmission behavior in real time. When it starts to fail, you can experience poor acceleration, rough idle, stalling, or even surging. Replacing it with a Walker sensor restores smooth throttle response, consistent power delivery, and reliable drivability, whether you're daily driving or putting your truck to work.

Built for long-term durability, the Walker TPS sensor is manufactured with high-quality, OE-matched materials that withstand constant movement, vibration, and heat found in the engine bay. Its internal potentiometer-style design accurately converts throttle movement into a stable voltage signal, ensuring consistent communication with the ECM over time. Engineered to meet OE specifications and tested for fit, form, and function, Walker sensors provide reliable performance, accurate readings, and long service life in demanding diesel and gas applications.
