I had made a post yesterday about my gas cap light coming on out of nowhere, and now today as I leave work, my Emissions Warning Light came on with a CEL. Car still felt the same, no power loss or anything like that. Looks like I am taking it in to the dealer tomorrow morning to have the issue diagnosed. Anyone have a similiar issue? Car has about 550 miles on it and I got it almost 3 weeks ago.

 

Prolly bad fuel cap or wasn't tightened causing large fuel leak DTC. Take to the dealer they'll clear the light

 

Yea the gas cap warning came on last night. I re-tightened it and after 3 startups, the light was gone. Drove the car this morning and it was fine. Went to leave work and the Emissions Warning Light came on. Not sure if it could still be the gas cap or something else that is more major.

 

Yep that is what came back this morning. EVAP codes for both large and small. The tech re-tested the EVAP system after the codes were reset and it came back as passing.

So weird since I never left the gas cap loose at all. I did top off the tank on my last fuel fill up though, and I have heard that Acuras are sensitive to overfilling. Not sure how much truth there is to that.
