How I Fixed P0420 / P0430 on My Jeep | O2 Sensor Spacer Hack

Got a P0420 / P0430 check engine light on your Jeep? In this video, I show how I used an O2 sensor spacer hack to address the issue on my Jeep and walk through the tools I used along the way. If you’ve been dealing with catalytic converter efficiency codes, this may give you another option to look into before throwing expensive parts at the problem. I also show the scan tool I used to read the codes and the tools that helped get the job done. As always, I’m sharing what worked for me on my vehicle. Be sure to diagnose your issue properly first, and always work safely.
