When this happened on my sister''s car I just broke the body of the O2 sensor so I could reach the hex with a full socket I also didn''t have one deep enough to use even with the wires cut.

I think I may be able to reach it if I remove the front right tire, remove the plastic protection piece that covers the suspension components.
Dec 10, 2019· Spray the penetrating oil on the O2 sensor and allow it to sit for a good 2030 minutes or overnight would be even better. Afterward, use an O2 sensor socket wrench to break loose the O2 sensor. Sometimes, due to tight spaces, you may have to use a regular metric or standard wrench. Some of the common wrench sizes are 22mm and 27mm or 7/8”.
