2004 6.0L Excursion 82K. Over the weekend the check engine light came on. I pulled a P1335 Code (Position sensor min stop performance) code with SGII, so i cleaned egr valve. It was sooted but not wet or gummy. Intake looked a little sooted and was dry. I cleared the P1335 Then it threw a P0404 (Exhaust Gas Recirculation Egr open code). Truck runs great. My question is does the truck need to cycle a few times for the check engine to go off?

Thanks Jason

 

You probably need to replace the EGR valve for the light to go off since it's bad.

 

Ok. I thought maybe i could get away with cleaning the valve. I have an extended warranty so ill take advantage of that.

Thanks
