i used the jumper trick this time after the CEL came back on today after 78 miles of being off. it said this

90 Evaporative Emission Control System leak detected in the fuel tank area.

so i fixed the charcoal canister so its not that now. what could it be.

also, ABS system threw an 11 - wheel senor (open/short to body ground/short to power) FR. what could i do to fix this?

 

Gas cap.

 

yea i thought about that, i didnt see any visible signs that it was bad, but i might as well go through the gauntlet of everything it could be. i'll buy one tonight. any other ides besides that

 

The cap could be slightly loose or it could not be holding enough pressure. If it is not that, it could be the filler neck, etc.

 

If you don't mind me asking, what was the problem finally? I have the same issue and my cap seems fine. Thanks!

if you're due for an inspection soon there's a machine they use to test your gas cap

 

Yeah, we don't have inspections in Alberta yet...I'll just buy a new cap and see it that fixes the problem...that is the cheapest place to start. I'll post when I find the answer. I see a lot of threads asking the same question but not a lot of completed threads after the problem is fixed. Thanks for responding though Lmike6453.
