I have never heard of an EGR setting off the Engine Light. Mine had 4 egr codes in it when I checked it due to the egr valve being unplugged, however it did not show a check engine light. Maybe you have another problem.

I had the same problem when unplugging the EGR. It appears that Cali emissions trucks use a 5 wire harness instead of the standard 4 wire. The extra wire must set off some sort of sensor or something that turns on the check engine light?

captain diesel,
No, I hooked mine back up and removed battery cables to reset any codes and the light. I am hoping that someone around here with much more brain power and insight than I will figure out how to cure the check engine light when this is unplugged. Good luck.

It won't hurt to leave it unhooked but that light will get annoying. I just pulled mine and went for a drive to see if my light would come on. My light didn't come on and it runs fine. Maybe even a little more responsive. Mine was bought in Idaho and is from Canada though.
