Bank 1 Sensor

[Geno]

Hello,

I need a little information on this sensor. I know there is two oxygen sensors before the Catalytic Converter. I think I have located both the sensors but the one that is bad is called the Bank 1. Would this be the one that I can see at the front of the manifold from underneath the hood or the one underneath the vehicle but before the Catalytic Converter. Any help ont the location would be greatly appreciated. These sensors are expensive and I do not want to change the wrong one ( I think they are interchangeable)

Thanks

The Bank 1 Sensor is underneath the vehicle before the catalytic converter. You cannot see it from above - you must get underneath your vehicle to access it.
