Fault code
2D20 - P2138

Fault text
Accelerator-pedal module, pedal-position sensor,
plausibility between signal 1 and signal 2

Fault description
Throttle/Pedal Position Sensor/Switch 'D' / 'E' Voltage
Correlation

Condition for fault identification
Test condition:
Pedal-position sensor monitor
Terminal condition: Terminal 15 ON
Voltage condition:
Voltage in onboard electrical system >= 10 V

Condition for fault memory entry
0.02S

Action in service
1) Check: Pedal-position sensor voltages [Pot voltage 2 =
(Pot voltage1)/2]2)
Check wires from DME to PWG,
3) Visual inspection of plug terminals (on components,
wiring harness and DME),
4) Replace PWG
