My 2013 Tahoe has been having an issue where it'll be running fine, then the Check Engine Light comes on. Engine Reduced Power alert comes on as well, as the TMS Control light and Stabili-Trak light. It'll reduce my speed so, I can't go over 20-30mph, max. The dealership says it's flagging a Low Five Volt code. After they replaced the battery, it still occurs. Has anyone encountered this, if so...what was the fix? The dealership is still troubleshooting this, too.

 

says it doesn't apply to the 2013, but this was the issue w/my 09.

my 09 also had the TPS error code.

 

Did replacing the TPS, fix your issue after that?

 

Yes, I replaced the whole assembly for I think $140 or so from Advance Auto. use code P20 at checkout online to pickup instore. 20% off.

no issues since it was replaced.
Wife said the dash lit up like a x-mas tree with errors!
