Suzuki Isuzu Throttle Position Sensor 13420-86G01 Throttle Opening Detection

Is your vehicle experiencing rough idle, acceleration stumble, or slow throttle response? These symptoms usually indicate aging throttle position sensor (TPS), causing ECU difficulty detecting throttle opening. This sensor monitors throttle angle in real time and transmits signals to the engine control unit to precisely adjust fuel injection and ignition timing, ensuring smooth power output. OEM number 13420-86G01; fits Suzuki and Isuzu series models. Installation notes: disconnect the battery negative first; ensure sensor mounting aligns with throttle shaft to avoid signal deviation.
