P0191 is injector pressure sensor system performance. Nothing on the other code with the letter mixed in. I would erase it and see if it comes back.

Check engine light


Go here and it will tell you how to get your codes. Actually on an 06 you can just turn the ignition on and off 3 times (dont crank the engine) and the codes will show up on your odometer. But here are all the codes. PS you can get a manual on pdftown.com for free too.
