I am replacing the O2 sensors on my 2012, and I am struggling to remove the passenger rear sensor. Does anyone have any pointers? I can not get it to budge. Help!!

Soak it in penetrating oil for at least 15 minutes. Use an actual penetrating oil, not just a basic lubricant like wd40. Do you have an o2 sensor socket?

Yes, that’s exactly what I did too. Seems to be seized up really tight unfortunately.

02 sensor socket on impact wrench - after the sensor has soaked overnight and low power on the impact to knock it loose.

In addition to above, heat with a torch before applying too much force. Might even try tightening just a smidge, apply penetrating oil again and then loosen. Repeat all the above and rock it out.
