Engine warning light illuminates

There has been a complaint of a drop in performance during the acceleration phase in the above vehicles.

The engine warning light (malfunction indicator light, MIL) illuminates and the following error codes may also be stored:

The error codes listed above all refer to an issue in the area of the accelerator pedal sensor (figure 1).

In this case, insufficient contact in the connection between the accelerator pedal sensor and the connector (figure 2) is responsible for the above-mentioned problem.
