Most O2 sensors usually have some sort of plug at the other end of their wires that connects to another set of wires, maybe you can remove the damaged 02 sensor from the cat and the remaining wire connected to the main wires through a plug by disocnnecting the plug and attachingf a new o2 sensor. Oddly enough, I had to work with a leaking oil pressure switch that was no different from disconnecting an 02 sensor and its wire from the existing wires through a plug

Is it possible to bent, snap or crack a car frame like this? I'm kind of feeling very scared at the idea I may have snapped, cracked or bent a Holden Viva's underside by placing a hydraulic trolley jack under the car and aligned it with the rail that was meant for another jack. I then started to raise up the car, when all of a sudden, this really loud pop sound came occurred from either the hydraulic jack being on a stony surface or somewhere along the car. I already checked the side where it was raised up from and saw no cracks coming from the jack point. I even removed the rubber undercoating to see if there was a crack coming from this jack point. I am genuinely scared that it might kill someone.
