Fault text
Throttle valve, throttle potentiometer: plausibility Timing
fault between potentiometer 1 and potentiometer 2

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

Condition for fault identification
Test condition:
If the deviation in the two voltages from sensors 1 and 2
exceeds a value defined in the application (characteristic
curve) the fault is recognized.
Potential problem source(s):
- Defect in wiring harness between throttle valve
potentiometer and DME
- Throttle valve potentiometer 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 throttle valve potentiometer
and DME
- Replace throttle valve potentiometer

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: none
- US emissions warning lamp: on
- US electronic engine power reduction: on
- CC message: on
