I was on the way to a concert with my girlfriend when I hit a pretty hard bump on the interstate. The abs, parking brake, wrench, and check engine light all flashed on. The abs and parking brake light disappeared as I pulled off the road. I cut the truck off and then back on and the wrench light was gone, but not check engine. My edge read the code as a p2106. I cleared the code and my truck seems to be running fine now. Any one else experience this problem? Why would it appear when I hit a bump in the road?

 

Here's a link to a good description of the code...

I would pop the hood and check the connector to the throttle body. I'd guess that large bump you had may have jiggled loose the connection of the throttle body wiring plug.
