Hi all, I wired up my dashcam a while ago, and pulled the wiring harness (big blue thing, see picture below). When I started the truck up it had a check engine light on (CEL). After a while it went away, I figured I unplugged a sensor or something.
Fast forward to 2 days ago I repeated the process for attaching my CB and sure enough, the CEL came on. However, this time it's not going away.
It's been over a 100 miles, at least 10 starts and stops. I've unplugged the battery for 2 hours, and also cleared the code using an old scanner I had, and the light came back.
Does anyone have any suggestions?
