things to try:
- Read our FAQ topic ("I have a check engine light")
- Search Scotty's youtube channel (type "p0420") into search box.

"Overall probably the biggest mistake vehicles owners make when they have a P0420 code is to simply replace an oxygen sensor (02 sensor). It is important to do proper diagnosis so you're not wasting money replacing parts unnecessarily."
Probably the biggest mistake vehicle owners make is buying a Hyundai or a KIA! HA!
