Code P22AB, where is the O2 sensor bank 1 Sensor 2 located?

This oxygen sensor is located right behind the catalytic converter. I am getting conflicting meanings to the code though, some say sensor 1, other says sensor 2?

P22AB - "NOx Sensor Heater Control Circuit Bank 1 Sensor 1"

So, I would change the one behind the cat first because that is the one that usually goes out. Here is the location. Make sure to clear the codes once the job is done. Check out the images (below). Let us know if you need anything else.

Thanks Ken, found it. The sensor seems to be a Bosch 0 281 004 800 (36532-51T-G01) but I'm struggling to find this online, especially linked to my Civic.

GSF Car Parts website suggests the correct part is a Bosch 0 281 004 579. Is it safe to go with this, as it looks identical to the sensor, I've taken off including the length?

Any better cheaper brands, or should I stick with Bosch? Thanks.

I have always liked Bosch so I would stick to that brand, also, go with the updated listing for the part as long as the electrical plugs match. Let me know how it goes.

Replaced with the above Bosch part number and DTC code wiped. Been driving throughout the day and all seems good. 150 Gbp from GSF Car Parts compared to almost 600 Gbp Honda! Thanks Ken.

Nice work!.. it sounds like you might have it fixed :)
