SOURCE: where is the oxygen o2 sensor located on 2004

I have a 2002 Impala with 3.8L, and just replaced my Bank1 O2.
It is located between the firwall and the middle of the engine, straight down past the spark plugs. Maybe 12 inches from the top of the engine.
As I recall the plug for the sensor is clipped to a bracket at about spark plug level.
I recommend using the crow foot style wrench to remove and install.

I have a saturn Ion and need to know where the O2 sensor is located. It is a 2006 4cyl 2.0. I am not sure if it is before the converter or in the rear of the converter.

There will be an O2 sensor before the catalytic convert and one after the catalytic converter.

On a four cylinder the one before the cat will be Bank 1 Sensor 1. The one after the cat will be Bank 1 Sensor 2.

Do you have a trouble code for an O2 sensor?

O2 sensor location

What engine do you have? Does your car have a V6 or a four-cylinder? Regardless of the engine, you will have an O2 sensor after the catalytic converter. On a four cylinder you'll have one in the exhaust manifold as well. On a V6 you'll have one sensor between the engine and cat, and one after each cat as well. The sensor(s) before the cats determine your fuel mixture, and the after-cat sensor(s) are used to monitor the efficiency of the cat.
