There are 2 different oxygen sensors for this car. I just replaced the back one which is in the exhaust system. If you go underneath the car and look near the catalytic converter. You should see the sensor threaded into the exhaust system. It will have a chord coming from it and heading to the engine. It will be plugged in at the rear of the engine. This is the more expensive O2 sensor. Just make sure not to cross thread the new O2 sensor as it will not get the correct reading. There are 2 different oxygen sensors for this car.
