O2 Sensor Replacement | 2012 Hyundai Accent (P0420 Code FIXED!)

In this video, I show how I diagnose and fix a P0420 code on this 2012 Hyundai Accent by replacing the Oxygen (O₂) sensor. Pretty simple on this car and minimal tools necessary. I explain this in the video, but in my experience this rarely fixes the P0420 code completely. Normally I end up having to replace the catalytic converter too, but for the price and the work involved, I like to start here and see if this fixes it.    / @benwrenchin      • Oil Change | 2012 Hyundai Accent      • Rear Brakes (Pads, Rotors, And Caliper) | ...      • Engine Mount Replacement | 2012 Hyundai Ac...   O2 Sensor https://amzn.to/3KL3FlJ O2 Sensor Socket https://amzn.to/3Xzp4Bj Swivel Head Ratchet https://amzn.to/480qzgu OBD2 DTC Scanner https://amzn.to/3YhoJ6o Fancy OBD2 Scanner https://amzn.to/3XDTt1n Burt Reynolds Bumper Sticker https://amzn.to/44c93oF *These are Amazon Associate links, meaning there is no added cost to you but a portion of the sale will go toward supporting the channel.
