Walker Pro 5/7/2013Hello Mike,
I am showing 3 sensors on this vehicle 2 upstream sensors and 1 downstream (all three cross to a Walker 250-24942). Cylinder 1 is on the passenger side of the vehicle. So Bank1 sensor 1 will be on the passenger side. It looks like the upstream sensors are mounted in the exhaust near the bell housing. The downstream sensor is mounted in the back portion of the catalytic converter.
If you have any further questions or concerns please contact us and we will be happy to help.
