Cat back exhaust
Cel intermittently light's up with code P-0420,( Catalyst efficieny below theshold bank 1.)
Fix is sensor signal comensator installed in the rear of the cat. As I understand 04 CAT's have 2 , 0-2 sensor's; sound's like a stupid question, but were is the rear o-2 sensor? Is it the one on the passenger side next to the oil plug?
