Ok so i have replaced both of my o2 sensors the downstream one was easy and has given me no problems but the upstream one keeps failing ( i have replaced it two times now, first two times i got an o2 sensor code now I am getting an 02 sensor heater circuit bank 1 sensor 2 code).
My question is what else could cause this problem... should I be looking at rewiring the whole harness for the o2 sensor here or something? For the short times that the o2 sensor goes bad i have not noticed a decrease in gas mileage or any hesitation or putters or anything.
As always you guys are awesome,
