Where are they at? How many I think there are 4? But what are the chances all four would go bad at the same time, the dealer says 3 of them are bad.

What tools would I need to remove/install?

Where can I find OEM for cheap?

Thanks!

2 upstream and 2 downstream.

It is more common for the downstreams to go 1st. Make sure you always replace them in pairs.

I just used an open ended wrench, but there is suppose to be a proper tool that does it.

That diagram is great. i got code 1146 for b1 sensor 2 and i was about to replace b2 sensor 1 lol. there is an o2 socket i borrowed from autozone. you can use a wrench but some of them are to hard to get at with a wrench. you get the $25 back once you return it. Thanks for the diagram Drock. you save me some time from a mistake lol.
ps. I'm only replacing 1...not a pair...i don't think its that big of a deal? rrod
