This throttle position sensor (TPS) is an electronic component that measures the angular position of the throttle plate, sending this information to the engine control module (ECM) to optimize fuel delivery and ignition timing. Built with high-quality electronic components, it provides accurate and consistent readings, unlike a faulty sensor that can cause erratic engine behavior. Operators may experience poor acceleration, rough idling, stalling, or a check engine light if the TPS fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing throttle position sensor often causes noticeable hesitation or stumbling when the accelerator pedal is pressed. The engine may idle erratically, surge, or even stall unexpectedly. If left unaddressed, these issues can lead to poor fuel economy and drivability problems, making the vehicle difficult to operate smoothly.

Installation Tip

Ensure the throttle plate is at its closed position and the sensor is aligned correctly before tightening the mounting screws. Do not force the sensor onto the throttle shaft; it should slide on smoothly.

Service Note

Clear engine diagnostic trouble codes (DTCs) after replacing the throttle position sensor and perform any necessary ECM relearn procedures.
