Fault text
Charge-air temperature sensor, plausibility: signal hangs

Fault description
The diagnostic function monitors the charge-air temperature
to determine whether it changes under conditions in which it
should change.

Condition for fault identification
Test condition:
The fault is recognized when the charge-air temperature has
not displayed a variation of at least 1.5 °C.
Potential problem source(s):
- Sticking sensor
- Shunt current
- Sensor manipulation
- Defective DME
Terminal condition: Terminal 15
Voltage condition:
- None
Temperature condition:
- When the engine is started the ambient temperature must
exceed -7.5 °C and be lower than 35.3 °C, engine
temperature above 79 °C
Time condition:
- (Drive vehicle at >40km/h for at least 120 sec., then allow
to idle for up to 60 sec. while stationary) x2 (execute routine
two times)
Other conditions:
- Engine must be running, TIA electrical diagnosis
completed

Condition for fault memory entry
10 sec.

Action in service
- Visual examination of plug/sensor for tampering
- Check sensor data/wiring harness
- Replace charge-air temperature sensor
- Replace DME
