Front O2 sensor, Bank One, sensor one
Here is original GM part. Bank one sensor one refers to the oxygen sensor before the catalytic converter. It is usually located in the downpipe coming straight off the exhaust manifold. You should be able to access it from the front of the vehicle. In some vehicles, there may be other components between the exhaust manifold and the rest of the downpipe where this sensor is usually located.

Note the note about it requiring GM to somehow integrate it into the engine management control system. No idea but probably necessary. So even if you install it, you may need to take it to the dealer to have it set up. I've never heard of this on a Saturn but this part fits a bunch of different GM cars.

From another GM parts site:

This states it's in the exhaust manifold/crossover as I mentioned above.

You will have an easier time with it if you disconnect the electrical connection first, and with the vehicle off, spray where it threads in with PB blaster to dissolve some of the rust. Wait 10 minutes. Start the car and let it warm up for a few minutes. The expansion of metal should help to loosen the connection. Use an oxygen sensor socket which can be purchased at any auto parts store. They usually fit onto the square part of a socket or the end of an extension.

Do not force it. Spray it a bit more and let it heat up a bit more. Do not snap it off.

GM usually used denso as the OEM partIf You do not use a denso or GM part, do not use Bosch and do not use one of the economy cheap ass parts.

I'm sure there are DIYs on other Saturn sites. None on ours for the Vue. Sorry.

Rockauto.com has great prices, but the shipping is ridiculous and usually brings the cost of a single part order up to the cost of other vendors. Especially for things that do not weigh much.

thank you!
