: p0403 Fingers 08-21-2007, 11:09 PM Stock trucks are getting 403's too. I am not sure why. The Stick does not prevent P0403s. I am thinking it is the EGR valve motor. seanosu 08-22-2007, 12:29 PM Thanks fingers, ive also got a p0406c code which is faulty egr valve. Is it hurting anything? Fingers 08-22-2007, 12:36 PM P0046C is a bad EGR valve. Cobra#3747 08-22-2007, 12:38 PM If the new updated ecm software dosnt take care of the P0403, more than likely needs an EGR valve. Its a control circuit fault seanosu 08-22-2007, 05:21 PM Where can i find new updates? Cobra#3747 08-22-2007, 05:24 PM have to go to the dealer | ||
