I have OBDII scan code of P0420 and I looked it up and has to deal with a low Bank 1 Cat Conveter.
What does this mean? Do you think its a Cat Coverter or an Oxy Sensor.
I would drive about 6 miles after I reset the light and it come back to P0420 each time.
Thanks for your time!
have the same problem?
