There are 4 O2 sensors on the car, do you have a specific code that's telling you which is bad?

Customer: replied 1 month ago.
no
Expert:  Mike V. replied 1 month ago.

Ok, like I said, there are 4 sensors, so if you can get the code it will help to know which one you want to replace. Many parts stores will get the codes for you at no charge. Please give me a moment to try and locate a good diagram showing them all for you.

Expert:  Mike V. replied 1 month ago.

I am not able to come up with a good diagram so let me try to explain their locations. When you open the hood you can see the exhaust manifold, One of the O2 senors is mounted right there. This is sensor 1, the back exhaust manifold also has a sensor just like this, these are sensor 1. Sensor #2 is after the catalytic converters. One for each converter.
