JP's truck's check engine light is on. It currently has P0420, and has some times shows P0463.
I am not as worried about the P0463 most said it was the tank sending unit.
Been using my Google fue best I can tell the P0420 is either the catalytic converter or oxygen sensor. Seems like most people said they needed to replace the converter.
I am assuming it would be the down stream O2 sensor?
Is there anyway to test the oxygen sensor?
