Fixed code p0420 in my 2005 PreRunner Double Cab Tacoma 1GRFE

This fixed code P0420 in my 2005 PreRunner Tacoma. I was worried it was the catalytic converter when I googled that P0420 code. I was already looking for an alternative catalytic converter, because the factory one is damn expensive. I continued my research and found that it could just be the O2 sensor. Swap and voila! The code is gone.

Pros

Handy thing

Cons

Good but not great
