My CEL comes on but only after I drive for about 5 minutes on the freeway.
If I disconnect the battery (to reset the light) I seem to be able to drive all over in stop and go trafffic and the light doesn't come on...but if I go up on the freeway and drive for a few minutes at 55+...."bing" light comes on and stays on until I reset it. P1040 (or whatever the EGR code is) I've had it checked each time at Autozone.
My question is about the DPFE sensor. If the DPFE was bad wouldn't my CEL come on right away when I started my truck? Does the fact that my CEL doesn't come on for a while mean the problem is with something else? Or could it still be the DPFE?
Looking for other people's DPFE success stories...did you light come on right away? Thanks for the insight.
