I have 4 working gps and a good decoy gp, so my OBD does not throw gp codes.
At some point in December I pulled the Espar for servicing, put a piece of pipe across the in and out hoses and kept driving. That was when I started getting OBD codes telling me the gp module was recording faults (sorry can't remember the codes). I cleared it, and it popped up again and did not self clear as the gp code does if I drive and do enough warm starts. I suspected a bad gp module, but as the van was generally starting well(except at (-20C) I figured I would work it out.
After I reinstalled the Espar, the CEL disappeared.
I have a pretty basic scanner, Autel 619.
Nothing really changed other than Espar out, Espar back in.
So I guess my scanner wrongly interpreted a line of code and called it GP module error(or something like that) and that a missing Espar throws a code?
I had thought the Espar was not actively communicating with the ecm.
