Fault text
Accelerator-pedal module, pedal-travel sensor 2, electric:
short circuit to positive

Fault description
The diagnostic function monitors the voltage of sensor 2.

Condition for fault identification
Test condition:
The fault is recognized when the voltage at sensor 2 rises
above 2.043 V.
Potential problem source(s):
- Defect in wiring harness between DME and accelerator
pedal module sensor 2
- 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 harness between DME and accelerator pedal
- Check voltage supply at accelerator pedal module sensor 2
for 5 V
- Replace accelerator pedal

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 or
clocking error, increased idle speed and no processing of
accelerator pedal data
