101F01 - P112F

Fault text
Throttle-valve angle - intake-manifold pressure, correlation:
limit value exceeded

Fault description
The diagnostic function monitors the throttle valve
aperture's plausibility relative to intake manifold pressure.

Condition for fault identification
Test condition:
The fault is recognized when the calculated mass flow rate
through the throttle valve is higher than the calculated mass
flow rate into the cylinders on Bank 1 by 65 %.
Potential problem source(s):
- Measured intake-manifold pressure (absolute) too high
- Vacuum/air leak within induction tract/crankcase
- Incorrect throttle-valve angle
- Pressure sensor defective
Terminal condition: Terminal 15
Voltage condition:
- Electrical system voltage > 10 V
Temperature condition:
Coolant temperature > -10 °C
- -10 °C < intake-air temperature < 90 °C
Time condition:
- Time after
- start
- > 0 sec.
Other conditions:
- Reduced dynamic response (load/rpm)
- 80 mbar < intake-manifold pressure < 800 mbar

Condition for fault memory entry
This fault is logged in the control module's fault memory if
it remains present for longer than 10 sec.

Action in service
- Check wiring harness from DME to boost-pressure sensor
and intake-manifold pressure sensor
- Check intake system and crankcase for leakage
- Perform learning routine for throttle-valve travel stops
