What's up all.
Ok, had my turbos rebuilt with CR performance upgraded CHRA's, and got the GH tune for the upgraded turbos. I have driven about 50 miles on them, and got the P2272 OBD code. So is this a known problem? Or just coincidence, and replace the sensor. I will call GH in the morning and ask, but for now, I wanted to find out what you all know.

Probably just a failing sensor. I would replace both so that they are both brand new.
Gearhead E30 tune, Gearhead intercooler, LMS firestorm hpfp, catted downpipes, corsa catback, 160 degree thermostat, 3 bar map, upgraded AD trans mounts, MSD coils, Nitto 555R drag tires on front, AR924 wheels and BFG sport comp 2 summer tires on rear, and an EPP intake.

You think the post cat sensors on both sides? Or both on the same side?

Bank 2 sensor 2 is the narrow band after the cat.... no need to replace the wide band before the cat...

I would agree with Ken and replace both narrow band O2 sensors which are AFTER cats in each down pipe.

And they are cheap so it is worth it.
