I've got a CEL on my ‘16 F-Type R, 40k miles. I’m out of normal warranty. I had the CEL scanned and it’s an oxygen sensor problem (code P2276-00, sensor stuck lean bank 2 sensor 3). What does this cost to fix? I found oxygen sensors online for $67, but I don’t know if they’re any good and I don’t know how much labor costs.

Also, I’ve read that there’s an emissions warranty (state or federal?) that applies for cars with less than 80k miles. Is this something I could use for this? If so, would I go to the jag dealer or would I go to an independent mechanic?

I would just get the O2 sensor and change it. They are easy to get to, especially that 3rd one on either side (car has 6!). Just make sure it is a good sensor (Bosch has a cross-reference of the Jag part, as they are likely the same OEM maker, and are at about the price you stated).

The labor time quoted for that rear one is 1.6 hours @ whatever rate the shop charges...So not too bad, if you do not want to try it yourself. It is a 7/8" O2 sensor socket, or flex wrench to get it.

Good luck.

Edit: Here are the locations of these O2s.

The rear would be the one on the left here
