Customer brings me this thing, has long tubes on it, the rear O2s disconnected/removed, can't seem to tune them out.
Have removed the related sensor 2 codes, disabled COT, what am I missing?
For some reason they always come back as either an MIL or a background code.
It also throws a traction control light he said started when they did this.
Did you uncheck SES Enable and set each code to No Error Reported? Seen plenty of tunes where people set the codes to No Mil Light and wonder why the code is still reading on scanners.
Posting the tune file might help as well
If the code says permanent, then it won't just go away. Over time it might. If he still has the rear sensors, just plug them back in and tie them up out of the way, it may stop a few codes from showing up.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
