My check engine lights comes off and on sometimes. I got it checked at autozone once and they pulled a code U1120 and they have no idea what it was. i called the dealership after looking it up on the internet and the DEALER didnt know what it was. ( or just didnt want to tell me without charging me!) I found on google "Lost Wheel Distance Message"

ANY IDEAS WHAT THAT MEANS?? Why does this keep turning on? It stays on for a day then goes off.

any help??

 

Maybe an ABS sensor located on the rear axel has water inside the harness or bad connection?

I'm new to this code but I'm thinking it's going back to a speed sensor.
