2007 Yaris O2 sensor removal

[Toolaholic]

Hi I changed out O2 sensor with a new denso. Ran to get exhaust hot. Removed with kroil penetrating oil / lisle O2 socket - Armstrong 11 inch long 11-994 locking 3/8 flex head ratchet. Installed with gearwrench 120 3/8 ratchet . Final 1/4 turn to 44 nm with a 22mm proto crowfoot and a flex head gearwrench 3/8 torque wrench. I didn’t remove cv boot guard. No pics apparently they are too big for Yaris world computer

The reason I didn’t remove boot shield is because I couldn’t see but only could feell fasteners . I was on my back , Yaris on ramps , head first sliding under from front. If I skid under feet first maybe I could of saw but/bolt holding shield. I actually had fun leaving it on and working around it with a fine tooth ratchet .
