Pedal position sensor
No correspondance Pedal position sensor B038 with B029.
Text-module
During calibration separate caracteristics are memorized for both position sensors. Both values are
permanrently compared durin operation. In case of a to important deviation, a failure code will appear.
No further consequences on vehicle operation.

Possible origin:
Mecanical attribution error of both sensors. Alteration of adjustment during operation
