O2 sensor location
Hey Everyone,
I need some help. I have heard different things. I have a code on my 2004 SS Monte Carlo with the 3800 for a bad O2 sensor: Bank 1 Sensor 2. My first question is how many O2 sensors does my vehicle have, and second question is where is this faulty O2 sensor? Any videos for reference or diagrams, would be greatly appreicated!
Thanks in advance,
AJ

Bank 1 Sensor 2 is on your downpipe after the catalytic converter. Just look under the car and you should see a U-Bend in the downpipe with the oxygen sensor sticking out the top if it.
Bank 1 Sensor 1 is on your rear exhaust manifold before it goes down into the downpipe.
