Subaru Throttle Position Sensors

The throttle position sensor (TPS) in a Subaru vehicle is a component that measures the position of the throttle valve and sends this information to the engine control unit (ECU). The ECU uses this data to adjust the fuel injection and ignition timing, ensuring that the engine runs smoothly and efficiently. If the TPS fails or gives incorrect readings, it can cause issues such as decreased fuel efficiency, rough idle, or stalling.
