So today I was checking fuses for a power seat, mirror, and pedal issue I have, and when I started the truck, the check engine light came on. It wasn't on before I shut it off, so I'm not sure if removing a fuse would of triggered it, or if I could have a different issue coming at the same time. I plan on getting it hooked up to a scanner in the next couple days, but its on my mind now, so I figured I'd ask here. Its on a 2005 Lariat, thanks in advance!

 

Not sure ! Pull the code first and start from there !
