Title: Pre-cat delete O2 sensor high resistance Post by: streacy on March 29, 2018, 02:22:59 PM Hi all,
I previous got help from a lot of you when deleting my rear 02 sensors and think you may be able to help me again. While doing my timing belt and water pump the car was lying up a while so I removed my down pipes and delete both pre cats. Great job car feels a lot better but now I am getting bank 1 & bank 2 front 02 sensors high resistance codes. I originally deleted my rear 02 sensors so this wouldn’t happen. Bearing in mind now my rear 02’s are still plugged in. I think it’s unlikely that both O2 sensors are gone, any definative way of checking them? Any help would be appreciated, thanks.

No engine light for a day then same high resistance codes on bank 1 sensor 1 and 2. Probably should post some logs, what should I log/look for? Thanks
