3.2.110. SPN 27, FMI 12, EGR Valve short cutΒΆ

Description

The EGR actuator short circuit.

Possible causes are:

  • The EGR actuator motor shorted to ground, battery or across the motor.
  • The EGR actuator is defective.

Reaction in EEM

The FC is stored and the warning lamp is activated. 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 EGR actuator wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
  • Check the operation with another EGR actuator to see if the actuator is defective.
