O2 sensor location

[Mattp69]

hi all
I have a 2006 Liberty and have gotten a 137 code that is a Bank 1 sensor 2 fault, does anyone know where this is? Is it hard to change?
Also, my driver side window regulator has gone on the fritz, is that hard to fix? I have Youtubes it and it doesn't seem entirely un-doable

Thanks
Matt

Bank 1 is the drivers side on the KJ and sensor 2 is the down stream O2 after the cat.Takes 30 seconds to change.

DO NOT USE A BOSCH O2 SENSOR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Only use OEM or NTK O2 sensors on your Jeep.

My o2 sensors are reading a fault after almost 10 years. Good to know not to use Bosch. Thanks.

If you're not in a hurry to get them, herko sells OEM or ntk sensors (I forget which) for under $30 shipped.

ETA: They ship priority mail so you should get them in 2-3 days from Florida.

Is bank 2 sensor 1 closer to the engine or back? I know its the passenger side. Thanks
