Is the p2202 NoX sensor replacement a NOx?
Hey guys, 1st post. 2012 LML with 192,xxx miles, so it’s out of all warranties. I am throwing a P2202 and P2203 without the MIL / CEL actually illuminating, and no reduced speed warning on the DIC.

What should I replace my NoX sensor with?
There is a “nitrogen oxide sensor reset procedure” that needs to be performed when replacing the sensor. UPDATE: Truck was throwing p2201 p2202 2203 p12b6 p2bad I replaced NOx sensor 1 with ACDelco 12671387 and all is well!

Is the p2202 NoX sensor circuit low bank 1?
According to what I read, P2202 is NOx Sensor Circuit Low Bank 1. Here is what I have checked: 1. Removed both the front and back NOx sensors on exhaust and both looked clean. I can see discoloration on the metal from heat, but not build-up.
Which is diagnostic trouble code for NoX sensor circuit range?
P2201 is a diagnostic trouble code (DTC) for “NOx Sensor Circuit Range/Performance Bank 1”.
When does the NoX sensor warning go away?
After a week of driving, probably over 500 miles and at least 20 engine start/stop, the front Nox sensor warning definitely have gone away (still have the old error code, P2202, saved in my OBD reader). Normally, if I was to clear the error, it will return after about 30+ miles.
