10BA4F - P10D2

Fault text
Charge-air temperature sensor, plausibility: Charge air
temperature too high

Fault description
The diagnostic function monitors the charge-air temperature
to detect implausibly high figures.

Condition for fault identification
Test condition:
The fault is recognized when the boost-air temperature is
more than 24 °C above the intake-air temperature.
Potential problem source(s):
- Defect in wiring harness between DME and charge-air
temperature sensor
- Charge-air temperature sensor defective
- Charge-air temperature sensor has been tampered with
- Defective DME
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
Drive vehicle at a speed above 40 km/h for at least 2
minutes to reduce the charge-air temperature, then allow the
engine to idle for at least 2 minutes to allow the charge-air
temperature to rise again. This sequence must be repeated
3x.

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 charge-air
temperature sensor
- Replace charge-air temperature sensor
- Replace DME
