Hi all, long time lurker, wanted to thank you all for the great advice that I have gotten from here. I now have a problem that I cannot find any info on. I am getting a code p2254. O2 bank 2 sensor 1 neg current circuit open. I just changed the radiator before this code came up. I appreciate all replies.

Check and see if you left anything unplugged. Check all plugs in the area. Reset code and see if it comes back. Not sure if bank 2 is the front bank but if it is that would put senser 1 in the exhaust in that area. Have a close look at it.

Bank two is indeed the front one and sensor one is visible from the top, under the hood.
Did you unplug it, the connector is right next to the radiator?
