Sorry Ronsetto, It's an Auto Question

12/24/2021 6:18 PM

2013 Buick, 1,8 non-turbo is giving me a 7AE and 7AB code.

It is running in "limp" mode, or at least retarded speed. I have not seen this mentioned in any sites I have visited. Some suggested it may be the cat. but my OBD-II shows no Cat codes.

The 7 codes, some suggest, are just warnings, but nobody can explain the limp mode activation in the car, yet.

Not going to try to repair it myself, but would like to have a clue when it goes to the shop.

Thanks

Means you didn't read how to use your scanner, they just show that their are codes you needed to continue to the next screen / menu to get the actual code...
