Hi,

Just got our CX-9 08 about a week ago and it has ran great. Yesterday the check engine light came on after inspection it appears I’m getting P0059. I got the new sensor but I’m having trouble locating Bank 2 Sensor 1. I know it would be in the front by the engine, but is it the sensor by the radiator or behind the engine ? Any and all help appreciated, thank you.

 

Not sure if this will help, as it talks front left and front right. This is from Mitchell's for my 2009, so should be the same as yours.
