Fault text
Boost pressure sensor, plausibility: Charge-air pressure too
low (not plausible in rel. to pressure before turbocharger and
ambient pressure)

Fault description
Under certain operating conditions (start, shutdown, specific
operating points) the barometric pressure sensor, exhaust-
gas backpressure sensor and boost-pressure sensor are
crosschecked for mutual plausibility. The DTC is logged
when the boost pressure differs from the other two pressures
by more than -130 mbar and their difference is less than
150 mbar.

Condition for fault identification
Test condition:
-
Voltage condition:
-

Condition for fault memory entry
Debounce (500 ms)

Action in service
1. Check wires and plug connections.
2. If wiring and plug connections are OK:
Replace boost-pressure sensor.
