Fault text
Intake-air temperature sensor, electrical: signal not plausible

Fault description
The diagnostic function monitors the voltage of the intake-
air temperature sensor on the engine-side of the air filter to
detect jumps that violate the specified level.

Condition for fault identification
Test condition:
The fault is recognized when the difference between the raw
voltage value and the low-pass-filtered voltage is greater
than 0.6 V.
Potential problem source(s):
- Defective wiring harness between DME and intake-air
temperature sensor
- Intake-air temperature sensor defective
- Defective DME
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 intake-air
temperature sensor
- Replace intake-air temperature sensor
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
None
Possible apparent symptoms:
Engine runs roughly
