Strange SEL light, It ONLY comes on when the vehicle is full of fuel, while ascending ONE local hill near Little Falls. No other hills seem to trip it and nothing else has ever turned it on. NO Codes set and no pending. Light stays on for 5 drive cycles and clears itself.
What I think may be happening is that this hill is a long climb and maybe the fuel is backing into the fill tube and getting drawn into the vent due to the higher vacuum at the time. I just don't get why it isn't showing any related codes. Anyone have a suggestion?
