O2 sensor question
Does anyone know what sensors are what. I hooked my car up to a tech2 and have an O2 sensor that is bad(voltage to high). On the tech2 it only shows 3 sensors. Is there only 1 on the drivers side and 2 on the passengers side?
There error is showing bank 2 but what are the sensors called pre and after cat? It sensor 1 pre cat?

Check the wiring and connections before condeming the sensor. It is more than likely bad but cover the bases.

I pulled a 141 code a couple years ago bank 1 sensor 2. Divers side post-cat.....About $55 to buy and replace didn't even use the special tool with the split socket for the wires to go thru took it back and got my money back.....
