your code reader cannot read this fault ,manufacturers only pins are used in the OBDII connector and they are copyrighted so snap on and autozone havent got the equipment to test them .Dealer only,your lucky because in europe its only cars from 2005 that have OBDII connectors and evan then the software is encrypted to stop yours truely ,and where does one get an OBDII cable with all 17 pins connected ?? answer you cant because their copyrighted to each manufacturer

SOURCE: where is the engine filter
If I recall correctly, its at the trailing end of the engine and gets unscrewed from below. If you want to replace it don't forget the light coating of oil to seal the seal!

In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
