Fault code
104611 - P1255

Fault text
Absolute-pressure sensor, intake manifold, plausibility:
intake-manifold pressure too low

Fault description
The diagnostic function monitors the DME's barometric
pressure sensor.

Condition for fault identification
Test condition:
The fault is recognized when the voltage of the barometric-
pressure sensor > 4.5 V.
Potential problem source(s):
- Internal DME fault, because barometric-pressure sensor is
located in the DME ECU; sensor voltage above threshold;
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- 5 sec. after engine off
Other conditions:
- Shutdown phase

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check air-induction system (wastegate, etc.)
- Check air-induction tract between turbocharger and intake-
air plenum
- Check wiring harness between DME and boost-pressure
sensor
- Boost-pressure sensor
- Replace DME

Fault effect and breakdown warning
Breakdown notice:
- none
Possible apparent symptoms:
Best case scenario: None
