This morning, the van dinged at me and the word "gascap" appeared on my odometer. No codes or check engine lights.
I fiddled with the cap, cleaned the cap and replaced it after resetting the odometer.
Warning came back on after restarting.
Bought a new gas cap. No difference.
Like I said, it's not throwing any codes or tripping any other warning lights. No driveability issues either. Just annoying.
Any ideas what else I should look for?
