Fault text
Throttle valve, adaptation: Re-teach, lower limit position not
taught in

Fault description
During the throttle valve adaptation routine the diagnostic
function monitors the offset and amplification of throttle
valve potentiometer 1 in the amplified range.

Condition for fault identification
Test condition:
This fault is recognized when the amplifier's offset exceeds
0.1 V or drops below -0.1 V. This fault is also registered
when the amplification factor is greater than 4.15 or less
than 3.85.
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:
- Engine warmed to normal temp, above 80 °C
Time condition:
- 30 sec. after Terminal 15 on
Other conditions:
- Engine on
- Vehicle velocity = 0 km/h

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
