First you will need a 7/8th inch wrench ( I cannot remember the metric size of them off hand) or an O2 sensor socket and appropriate ratchet.
Bank one will be the left side of the motor which in your case would be the FRONT bank of the engine as it sits in the vehicle. Usually the O2 sensors are mounted close to/or in the exhaust manifolds, so crawl under the car, and follow the front exhaust pipe from the front exhaust manifold back towards the catalytic converter. You should see it somewhere near where the pipe bolts to the manifold (looks almost like a sparkplug).
Once located, Unpug the connector, compare the old and new/replacement sensor connector to make sure you bought the right replacement, use the wrench/socket and unscrew (not always easy) the old one. Install the new sensor. It does not need to be cranked in there for oblivion, just a little tighter than %26quot;snug%26quot;, reconnect the connector and route/tie the wires where they wont interfere, hang down, drag or burn on the exhaust.
Use a scanner to clear the EDC.
If I have the correct scanner, I usually run the car and observe/verify that the new sensor is working properly before clearing the code and sending it home. If you can't, just clear the code.
All done
Sometimes the sensors are hard to loosen. I usually try to do it when the exhaust is still hot, they come out easier. But this also means that I get burned sometimes.
