My check engine light came on, and the code (136) indicates the 'Bank 1, Sensor 2' oxygen sensor is bad. Does anyone know exactly where this sensor is located, and how difficult is it to replace?? I have replaced sensors on other vehicles, so I am familiar with how they can seize themselves to the exhaust component that they are screwed into, but what I am wondering is how accessible this sensor would be. Any thoughts or advice would bemuch appreciated.

Its usually pretty easy if you have a lift. The sensor does not cost to much and you can take care of it yourself the dealership will charge you huge for it so stay away from there.
