O2 sensors

[Goldenzrule]

Are all 4 o2 sensors the same or do you have to order specific skus for each?

There are two part numbers for the O2 sensors, one for the pre and one for the post. The part numbers are 56029049AA is your post-cat O2 and 56028994AB is your pre-cat O2. There is no specific for Bank 1 or Bank 2 (left or right), so the pre-cat O2 sensors are interchangeable with each other as are the post-cat O2 sensors with each other. Your pre-cat sensor is heated and the post isn't, so try not to mix them up or they won't work correctly.

Great info . Thank you. Google didn't help me find the answer so I really appreciate your response.

You may want to give the service manuals posted in the forums here a try as well. There's loads of useful information, including part numbers for sensors, body panels, lights, etc. They're located in the DIY section of the 3rd Gen Forum.
