Help..CEL code P0057 HO2S heater control circuit low(bank2 sensor2)
I need help to find out is this a upstream or downstream issue. If it's upstream issue which o2 sensors do I need to look(near)?And it's downstream issue I guess o2 sensors near rear exhaulst pipe? Any input will be appreciated, thanks

Haynes manual lists upstream sensors as 1/1 and 2/1, downstream are 1/2 and 2/2. I'm not positive but I believe bank two is the passenger side so check the o2 sensor on the passenger side cat. If it's bad it's a good idea to change the o2 sensor in the other bank at as well.
The best thing to do is get pipes and turn the rear o2 sensors off so you never have to worry about another cel from them.
