  • 02 sensor

    My service engine light is on and i got it checked out , i think the code is
    P0420 , its one of the o2 sensors , i think its before the cat, but the thing is i have a straight pipe on it , i was wondering if that is the cause , and is it even worth changing it?

    no, its not worth changing
    its either the before cat sensor or the after
    on mine I only have an after cat sensor
