20504685 — Throttle Position Sensor 20504685 1063332 3175130 For Volvo Fh Fh12 Fm Fm12 Fm9 Truck

This throttle position sensor (TPS) is a vital input to the engine control module (ECM), accurately reporting the throttle pedal's position to regulate fuel delivery and engine performance. It converts the mechanical position of the throttle into an electrical signal, differing from a worn sensor that may provide inaccurate or fluctuating readings. Operators may notice poor acceleration, erratic idling, engine hesitation, or the check engine light illuminating when this sensor malfunctions.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

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

Failure Symptoms

Symptoms of a failing throttle position sensor often include a noticeable lack of engine power during acceleration or hesitation when the throttle is applied. The engine may also idle erratically or stall unexpectedly. If left unaddressed, these issues can lead to poor fuel economy and potentially trigger limp-home mode, severely restricting vehicle performance.

Installation Tip

Ensure the throttle body is clean and free of carbon buildup before installing the new sensor. Do not force the sensor onto the throttle shaft; it should slide into place with minimal resistance.

Service Note

Check the throttle body for proper operation and inspect the intake air system for leaks when replacing the TPS.
