I have a 2012 5.0 and I have a U0422 code. No check engine light is on and truck is running fine. Going to take it into the dealer next week, but has anyone seen this code and have any idea what could be causing it?

 

I think it means your 5.0 will be replaced with a 3.5.
This link may help more.........

By the way, I love my 3.5

Oh great now I will have even more problems! All kidding aside, my code reader told me what it was. From all my searching I could only fine threads on that code associated with the 3.5 not a 5.0. Guess I will find out more on Monday when it goes into the shop.

 

U0422: invalid data received from body control module.

I had the same code pop up the last time I tuned my truck. I asked tech support at Hypertech about it and they basically said its nothing to worry about. "U" codes are used to display tiny glitches between the many computers that communicate with each other throughout the vehicle.

I hope this helped!

 

Did you ever figure out what this was?
