How do you clear a permanent code?

OK, some very smart person has figured this out. How to get rid of a permanent code.

P0068 - MAP / MAF - THROTTLE POSITION CORRELATION (PERMANENT)

I made a change to my tune and threw 3 codes, one is permanent see attachment.

Thanks, Victor

You don't, it's permanent.

Either the issue has to be fixed or it goes away on it's own. Or if said code is not causing an issue you can disable the SES light.

Yep. I suppose that the MAF, VVE (MAP), or throttle related tables were changed enough to pass the disagreement threshold. You could reverse the changes you made....but if the changes were going in the correct direction that proves that the other thing (probably either MAF or VVE) also needs to head that direction....so they can stay in agreement.

Once your computer sees that they agree again....for a little while....the code will clear on its own.

I have disabled it in the DCT temporarily till it clears, I also rolled back to an earlier tune that did not have any issues. I am told by a good friend that it will clear it self in time.
As you have posted. Thank you!!

This is the change I made, trying to get my cold start surge under control.....
(your surging bad because your commanded afr at startup is at 9afr way to rich - go to fuel/open loop/gas gear and gas p/n - copy p/n to the in gear chart and see how it starts up if it still surges then lean out the fueling a bit more)

Drove the car twice and code went away!!!!!!!

Thank You!!!!
