20729579 — Throttle Position Sensor 3985226 20729579 82627975 21116880 For Volvo Fh12 Fm12 Fh16 Truck

This is a Throttle Position Sensor (TPS), a vital sensor that measures the position of the throttle pedal and transmits this information to the engine control module (ECM) in Volvo trucks. Manufactured to precise Volvo standards, it ensures accurate fuel delivery and engine performance, unlike a worn sensor that can provide incorrect readings. Operators may experience poor acceleration, engine hesitation, or increased fuel consumption when this sensor fails.

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

Erratic engine idle, poor acceleration, engine hesitation during load, or illuminated check engine light with related diagnostic codes. If ignored, it can lead to reduced engine power and increased fuel consumption, impacting operational efficiency.

Installation Tip

Ensure the engine is completely cool before starting installation to avoid burns. After installation, it is crucial to perform a throttle relearn procedure as per the service manual.

Service Note

Inspect the throttle body and accelerator pedal assembly for any signs of wear or damage when replacing the throttle position sensor.
