Where Is My Car’s Oxygen Sensor 1 Bank 2 Located
Posted in Oxygen Sensors | Asked on Aug 20, 2010What does bank 1 and 2 mean? How can I tell which is which?
My car has the “Service Engine Soon” light on. I scanned it and got the message “…the response time for oxygen sensor 1 in bank 2 was too slow during testing.” What does this mean? Thanks!
Sorry… 98 Infiniti i30

It meens you have more than 1 oxygen sensor.When you ask this type of question you need to let us know,make,model,year,of vehicle.You can go to autozone website and they have a section in there where you can get diagrams and how too info.
Bank 1 is on the side of number 1 cylinder. Bank 2 is the other side.
Sensor 1 is before the catalytic converter and sensor 2 is after it.
The computer ran a test and the O2 sensor was to slow to react. It may be the sensor but proper testing is in order to be sure.
“Bank” means either left or right depending on the set up of your exhaust system. In a true duel exhaust system, you have 1 catalytic converter on each side of the system. Bank 1 can mean left catalytic and Bank 2 is the right. Sensor 1 is the one before the catalytic and sensor 2 is after. Your sensor before the cat. is going bad.
Bank 1 is on the side of number 1 cylinder. Sensor 1 is on the exhaust manifold.
You have 4 O2 sensors, just replace the first sensor on the passenger side of your car, bank 2
