My check engine light came on and Autozone pulled P0133 (bank1, sensor1 O2 sensor) and P0420 (catalyst below threshold) codes. About a week later, while driving the CEL light went out and hasn't come on again. Question: are the codes still in the computer? Another question: is bank 1 the driver side or the passenger side on the 1996 OHV V6? Finally, the truck has 62,000 miles. Should I just replace both O2 sensors upstream of the converter under the assumption that if one is bad (or going bad) the other can't be far behind?
Thanks.
Thanks.
