    7th Injector fault. On the next stop check the harness to the 7th injector. If you can put some dielectric grease in the connector. Then see if you can do a parked regen. If that doesn't work then you are going to have to replace the 7th injector.


    Couple of questions. How many miles? Has this ever been replaced or cleaned?.
