My 2004 cherokee limited 3.7 petrol is pulling up the code P0157, which suggests a problem with the Bank 2 downstream 02 sensor. Forum users post that bank 2 is the passenger side cat, however as mine is a right hand drive jeep based in New zealand, Is it on the driver side? I unplugged it then gave it a run and had no change in codes so I'm reasonably sure, but if someone could confirm that would be great.
