I went to Autozone to pull the code for my SES light, they said the O2 sensor, Bank 1, Sensor 1 is bad. Where would this O2 sensor be located?

 

I'm not sure if bank 1 is the front or rear bank. Cylinder #1 is on the rear bank, so I would assume that its the rear bank. A more accurate answer would be to read the codes yourself first and see if you get either an 0303 or 0503 code.

 

is your car cali spec or not? the bank 1 is in the rear, my cars bank 1 sensor 1 is the upstream sensor on the side of the engine closest to the firewall, wheras the bank 2 is closest to the radiator. The plug for the sensor is on top of the engine, if u are looking at the car, its off to the left side, if u need ill post pictures tomorrow or the next day. its just as easy though to just look at the bank one side of the ypipe and follow the sensor wire up to the engine compartment, this should show u where the plug is. if u need help figuring things out pm me.

 

cant help you unless you say Front Left, or Front Right. pull the code manually
