| Good chance the egr valve is sticking. It’s on the right rear corner of the engine. SPN 27, FMI 7, EGR Valve position deviation
Description
The EGR actuator difference between the actual and the target shaft position is too high. The error will heal when the difference grows smaller.
Possible causes are:
The EGR actuator is defective.
The EGR actuator shaft is twisted or blocked.
The CAN bus 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 assembly to detect the defective control shaft.
Check the operation with another EGR actuator to see if the actuator is defective.
