Does your check engine stays on or goes away after a little while? Also when the check engine light comes on does it effect the car in any way?

It usually comes up under load and stays on. It doesn't affect the car at all. Just the yellow engine light on...

Oh ok, yes same here it will come on when I take off fast and usually when I take off fast few times, it will pop on and go away within 20-30 minutes, doesn't effect the car as well, looks like we are the only ones that have this problem 🤷*♂️, I will dig around here in Charlotte and see if anyone can figure out what it is, and if you figure anything out plz let me know and I will do the same 👍

Did anyone ever figure this out? I just started getting the code and its looks like it is a "permanent" code.

Likely torque intervention code. The TCU triggers this DTC when it doesn't receive torque information from the ECU for more than 2 seconds. Would explain why tuned cars are having the issue. The tuner didn't adjust the torque tables correctly for the given power output.

This DTC has nothing to do with the idle functions in the ECU. The TCU is what triggers the code, not the ECU. Per OBD, this is a "PCM" error -- Powertrain Control Module (otherwise known as the TCU).
