From VIDA:

The function of the accelerator pedal (AP) position sensor is to provide the engine control module (ECM) with information about the position of the accelerator pedal. This information is used by the control module to control engine torque.

The sensor consists of a plastic housing with two potentiometers, an AC/DC converter and circuits. The potentiometers are connected to a shaft which is affected by the position of the accelerator pedal (AP). The resistance in the potentiometers changes with the position of the accelerator pedal (AP).
The accelerator pedal (AP) position sensor transmits an analog and a digital signal (pulse width modulated (PWM) signal) to the control module. These signals indicate the position of the accelerator pedal (AP). The digital signal is generated by the sensors AC/DC converter.
The analog and digital signals are used at the same time by the control module to regulate the fuel volume.
The sensor is supplied with 12 V by the system relay via a fuse and is grounded to the body.

The digital signal is used in conjunction with the analog signal for accelerator pedal (AP) position sensor diagnostics. The accelerator pedal (AP) position sensor signals can be read using VIDA. A diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects a difference between the analog and digital signals. The engine control module (ECM) then uses a minimal value to ensure the function (limp home).

The accelerator pedal (AP) position sensor is located on the accelerator pedal bracket.

Good luck.
Don’t suppose I could clean the contact areas ect before moving onto further things....

Thanks
