Fault code
104610 - P1250

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

Fault description
During the shutdown phase the diagnosis function monitors
the DME to determine whether the ambient-air, intake-
manifold and boost-pressure sensors are measuring the same
pressure.

Condition for fault identification
Test condition:
The fault is recognized when the intake-manifold pressure
sensor deviates from the average for the pressure sensors
(barometric pressure, boost pressure, intake-manifold
pressure) by more than 70 mbar.
Potential problem source(s):
- Defective wiring harness
- Sensor has been tampered with
- Sensor defective
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 wiring harness at sensor
- Replace sensor

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