Fault text
Throttle valve, throttle potentiometer 2: Signal implausible
for air mass

Fault description
When a single fault occurs at the throttle valve, the
diagnostic function monitors the operation of the remaining
sensor. The deviation in the sensor signal is plausibilized
against the default value from air mass.

Condition for fault identification
Test condition:
The fault is recognized when a defect at sensor 1 or a
clocking error [deviation between sensor 1 and sensor 2 >
6.3% throttle valve ] is detected and comparison between
sensor 2 and default value is greater than 14.9%.
Potential problem source(s):
- Defect in wiring harness between throttle-valve actuator
motor and DME
- Throttle-valve sensor defective
- AD converter input in DME 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 throttle valve
- Replace throttle valve
- Replace DME

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:
- Reduced power
