20499271 Pedal Sensor for VOLVO FH III FMX III FM III FH16 III Heavy Truck Replacement Parts

Product Introduction
The Accelerator Pedal Position Sensor 20499271 is an electronic sensing component designed for Volvo heavy-duty trucks. Unlike a complete pedal assembly, this product focuses on detecting accelerator pedal movement and providing accurate position feedback to the vehicle control system.

The sensor converts pedal displacement into electrical signals and transfers this information to the ECU, helping the engine management system determine the driver's acceleration demand.

The 20499271 sensor is used in Volvo FH, FH16, FM, and FMX heavy-duty truck applications.

Sensor Function
The accelerator pedal position sensor plays an important role in modern truck electronic control systems.

During operation:

The driver presses the accelerator pedal.
The sensor detects pedal movement.
The sensor generates an electrical output signal.
The ECU adjusts engine power according to the input.

This process replaces mechanical throttle linkage and improves communication between driver operation and engine response.

Heavy Truck Application
The sensor is suitable for Volvo truck platforms, including:

Volvo FH III
Volvo FH16 III
Volvo FM III
Volvo FMX III

These vehicles are widely used in long-distance transportation, construction, logistics, and heavy-duty operations where reliable electronic control is essential.
