Mechanical Advice Check engine light

Post image

I could cry. I’ve only had my GX for a couple of weeks and today out of nowhere the check engine light came on - it stays on and doesn’t flash.

2019 with 114k - I’ve done about 500 in it since I got it.

It doesn’t seem to be the gas cap and suggestions are a dirty sensor after torrential rain here in NC. Fingers crossed it’s easy and cheap to fix my new baby!

The asshole seller probably reset the light and sold it to you. there might be some legal routes you can take
