"service engine soon" light

[Nice rig]

On my way back from camping this weekend I stopped and filled my tank and not but 1 mile from the gas station my "service engine soon" light came on and stayed on. Stopped and checked the cap and that was good to go, doesn't run any different, but now I have this annoying light. Plan on going to Autozone to pull some codes tomorrow.

Come back and post when you have a code.

Well they pulled a P0140, so I went under and checked my 02 sensors and found one had unplugged. Plugged back in and had code cleared...all good to go.

Saved 70 bucks.

That's pretty weird. Those connectors are pretty secure and don't just come uplugged on their own.

Well....I did just get back from camping and had the truck be one with nature.
