Default 2C7E 2C6A 29F5 need help! - 06-29-2022, 03:33 PM

Just recently installed jb4 and ive been getting these codes, all 4 O2 sensors are brand new bosch, SES light came on after clearing it and resetting adaptation

29F5 ******* dp detected
2C7E lambda probe behind catalytic converter
2C6A no description found

I checked after a few miles of driving and im still on map 5 with SES light on , is it safe to keep driving with SES light on?

Any insight is appreciated.

2C7E can be an exhaust leak at the dp. smoke up the tail is how I found a leak on mine with that code.
