Many thanks for all your help. Is there a picture somewhere and more detailed instructions on how to replace the sensor? Is Bank 2 located in the exhaust manifold closest to the front of the car? Should I get the sensor (and socket) at Autozone or is it better to get the sensor at the Toyota dealer? By the way, my car is actually a 98 Sienna with a V6 engine...
