Default EGR Failure? P0403 coming up
Hi guys,

Having a bad run this week. New starter motor and all was good for a day, then the Jeep lost boost as I was driving. No turbo actuator codes this time, it's showing P0403 and that diagnoses as an EGR valve fault.

Has anyone here had this, and what was the solution? I am loath to spend $700 on a new EGR valve until I have some idea that it is the culprit.

Thanks all,

Rob
