P0054

08 5.3 sierra - had code for bank 1 sensor 2 So I changed it out with a Bosch OE sensor and now I have a new code P0054 - tried to change out with another Bosch sensor to see if will fix. If code comes back what should I do next?

Check wiring as well

What wiring an I checking?

I believe Chawkins6789 is refering to checking the wiring on and to the sensor backwards along the frame and what not to make sure it hasn't been chafed or broken.

Correct. Sorry late night doing homework and I am on the west coast so there may be a time difference

Ok it's been a month and the code hasn't come back. I tried 2 Bosch o2 sensors and had the code. put the AC Delco o2 sensor in and code stayed away.
