What Is a TPS Sensor? Symptoms and Location Details
Modern vehicles rely heavily on sensors to deliver smooth performance, and one small yet critical component often overlooked is the throttle position sensor. If your vehicle hesitates, idles roughly, or struggles to accelerate, this tiny device could be the reason. Understanding what is a tps sensor and how it functions can help you identify issues early and avoid costly repairs. What Is a Throttle Position Sensor A throttle position sensor (TPS) is an electronic component that monitors the position of the throttle valve in your engine. It is mounted on the throttle body and tracks how far the throttle plate opens when you press the accelerator pedal. This information is sent to the engine control unit (ECU), which then adjusts fuel injection and ignition timing accordingly. In simple terms, the TPS acts as a communication bridge between your foot on the gas pedal and the engine’s response. Without accurate data from this sensor, the engine cannot determine how m...
