2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 407
The control module initially tests internal function sequences after wake-up. If they are OK, all diagnosable outputs are then tested and any faults are
stored.
Control module wake-up through:
- event-induced CAN message
- wake-up signal via wake-up line
- key contact (terminal S)
- "Ignition on"
Possible fault causes
- Control module is incorrectly coded
- Periphery connected to specified control module is incorrect
- Control module faulty (in most cases the cause is not the control module but incorrect coding.)
Fault effects
- The specified control module sends only substitute values via the CAN.
- Other control modules detect these substitute values and set this fault code.

Diagnosis information - Control unit DME (DFI)
Accelerator pedal Potentiometer 2
Diagnostic conditions
- Ignition on > 3 Second(s)
- then Accelerator pedal complete depress > 3 Second(s)
- then Accelerator pedal complete undo
- then Idle speed > 10 Second(s)
Possible fault causes
- Short circuit to B+/ground/between lines or open circuit in the lines CLOSED Potentiometer 2
- Accelerator pedal Potentiometer 2 Faulty
Fault effects
- The system is in substitute mode.
- The accelerator pedal angle is calculated from the remaining potentiometer signal.
- Dynamic response is reduced.
