It had thrown that code off a week ago, then a couple days ago it went on again. They told me its probably my gas cap, that its not on good and all. So i replaced my key one for a regular one again. I reset the system again, and waiting to see if it comes on again. If so, what else can it be?

Also check the fuel inlet tube to the tank for cracks. I've noticed quite a few posts over the past year from people with body lifts experiencing that.

 

Ive actually been noticing when i start my truck its been idling kinda weird. Im pretty sure something like that is throwing it off. Thanks for the heads up, ill look into this and see if this will fix it.

 

my truck was throwing a code like that too...all I had to do was tighten the hose clamp on the filler hose and vent tube, I'd give that a shot too
