The EEM monitoring system has detected that the intake 1 pressure sensor value is implausible.

Possible causes are:

The sensor wiring is defective.

The sensor is defective.

Reaction in EEM

The FC is stored and the warning lamp is activated. Engine power will be reduced (Degradation Level 3). The CAN message indicates active fault.

Solution

Check the intake 1 Boost and temperature sensor wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).

Check the operation with another intake temperature and pressure sensor to see if the sensor is defective.
