I have had this come up (and go away) when driving recently and my power is cut dramatically (50 mph max) and get messages about servicing traction control and stabilitrac. If any of you have ran into this...what needed to be fixed??? The DBW gas pedal, throttle position sensor, or other???.

Thanks for your help!

 

whats the rough mileage?
factory TB?

 

Pretty sure this was a re-call... maybe check with the dealer first though

 

My truck has about 85k and is running the factory throttle body.

I did some more research and it sounded like it was the TPS in the throttle body assembly or a loose connection to one of the throttle body wires.

The good news for me is that I have a spare throttle body that is ported which includes a TPS.

I will likely swap tonight and see if my problem ever comes back.

 

Two guys I work with had the same issue. It was the TPS in the TB.

 

that's what I was getting at, cause a long while back I had received a letter from GM Canada saying if I had those issues to bring it in
