Fault code
103308 - P2138

Fault text
Accelerator-pedal module, pedal-travel sensor, plausibility:
synchronism fault between signal 1 and signal 2

Fault description
The diagnostic function monitors the mutual deviation
between the two sensor voltages.

Condition for fault identification
Test condition:
This fault is detected when the voltage differential between
sensor 1 and sensor 2 exceeds a specific defined value.
Potential problem source(s):
- Defective wiring harness
- Accelerator pedal module defective
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- none

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check wiring and plug connections
- Check voltage supply to accelerator pedal for 5 V
- Replace accelerator pedal module

Fault effect and breakdown warning
Breakdown notice:
- It is possible to continue driving the vehicle, but passing
maneuvers should not be attempted owing to the reduction
in engine output.
Possible apparent symptoms:
- Limit on pedal value variation and on maximum absolute
value (34.5% pedal)
- In combination with fault in accelerator pedal sensor 1
and/or 2, increased idle speed and no processing of
accelerator pedal data

Driver information
Warning light:
- ECE emissions warning lamp: off
- ECE electronic engine power reduction: off
- CC message: on
- US emissions warning lamp: on
- US electronic engine power reduction: on
- CC message: on
