The EEM monitoring system has detected that the intake pressure sensor value is implausible.

Possible causes are:

The boost air piping is leaking.

The EGR pipe is leaking.

The boost pressure sensor is blocked.

Reaction in EEM

The FC is stored and the warning lamp is activated. Engine power will be reduced (Degradation Level 2). The CAN message indicates active fault.

Solution

First save the error log and then erase it. Restart the ECU after erasing the error log. If the fault occurs again during the next driving cycle, check the following paths:

Check the boost air system tightness (piping, intercooler).

Check the turbo waste gate flap and the condition of the actuator. The actuator should move in the ECU initialization.

Check the condition of the turbo charger.
