Cupillac Posted May 19, 2006 Report Share Posted May 19, 2006 Hey there everyone, I was just driving from work earlier today and the Service Emissions System was displayed. Is PC1406 the correct diaganostic code? and what exactly am I looking at here?

KHE Posted May 19, 2006 Report Share Posted May 19, 2006 Sounds like the EGR pintle position code to me - time to clean the EGR valve. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
Cupillac Posted May 19, 2006 Author Report Share Posted May 19, 2006 WOW KHE, thanks for the fast reply. To clean the EGR, that has been posted several times...correct?? "Cadillac, it's not a car, it's an obsession" -W.Kingdon Link to comment Share on other sites More sharing options...
KHE Posted May 19, 2006 Report Share Posted May 19, 2006 WOW KHE, thanks for the fast reply. To clean the EGR, that has been posted several times...correct?? It should be in the archives. It is more difficult now with the stainless steel fuel rail - you will need to lift the rear bank of injectors out of the manifold to get the bracket off the EGR stud but it is still a relatively easy job.
