    Hi, I had the engine light popped up awhile ago and coded it and it said rear o2 sensor.... months and gone by and finnally had to change it because of state inspection...changed 02...then p0420 is now the new code..so I changed the cat. now...my question is..I cleared the code,,but after 11 miles it came back? i was told you have to drive it at least 100 miles for the computer to reset...then everything will be good? Any help ?
    thank you...

    Hmmm...........it doesn't say in the FSM. It's a 2 trip logic that will trigger it how ever. You could always disconnect the NEG BAT side for a few minutes and see if it comes back.
