Light kept on this entire time, even when I was parking it at work. Sign up. It's the third sensor down listed on the website I'm guessing?

Check out the link below: Nissan Murano o2 sensor Partsgeek. The reason you can make this determination is that a functional catalytic converter will lower the temperature of the exhaust by a substantial degree in the course of normal operation. Then screw the entire assembly back into the CAT.
