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 plausibility of the
voltages of the sensors in the accelerator pedal module.

Condition for fault identification
Test condition:
The fault is recognized when the difference between the
voltage from sensor 1 and twice the voltage from sensor 2 is
> threshold value (characteristic curve).
Potential problem source(s):
- Defect in wiring harness between DME and accelerator
pedal module, excessive contact resistance
- Accelerator pedal module defective
Terminal condition: Terminal 15
Voltage condition:
- None
Temperature condition:
- None
Time condition:
- None
Other conditions:
- none

Condition for fault memory entry
The diagnostic fault code is logged when the fault persists
for longer than 340 ms.

Action in service
- Check wiring harness between DME and accelerator pedal
module
- Replace accelerator pedal module

Fault effect and breakdown warning
Breakdown notice:
- The engine reverts to its limp-home program, continued
vehicle operation is possible but drivability is restricted,
because power is reduced the driver should refrain from
passing maneuvers.
Possible apparent symptoms:
- Poor throttle response
- Loss of power

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

Service instruction
- none
