it says its a heater circuit bank 2 sensor 1. I looked online and they're kinda pricey... is there anything i should check first before i just replace the sensor?

you can swap 2 sensors from the same position (up flow or downflow), so you can swap the bank 1 sensor 1 over and see if the code changes to the first bank, but i would say just replace it right away, its a pain in the ass enough to even get the first one out, let alone taking 2 out when you dont need to

got around to changing it out today. i dont know why you said it was hard. it was easier than changing a tire lol. the old one was pretty bad looking though. im betting it was original. the other one seems fine but maybe itll go soon too
i swapped out the sensor and wiped the CEL with my reader. i drove about 4-5 miles to test it out and no light as of yet. im gonna keep the reader in my glove box in case, but it would have come up pretty quick again if there was still an issue right?
