Oxygen Sensor
There are actually (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions.
You will need;
Oxygen Sensor Socket
Anti-Seized
Penetrating Oil
I have even used a small plumbers propane tank and heat it up and it help get them free.
Sometimes it will take 15 minutes or take a few hours it depends on your luck…

where is the oxygen sensor located on a 1997 Chevrolet lumina
All O2 sensors are threaded into the exhaust system at various points.
Oxygen sensors are located on the exhaust system. This one is on the exhaust manifold. The only oxygen sensors are on the passenger side on this year Ram.
There are two screwed into the exhaust on the rear of the engine.
how many oxygen sensors are on a 1997 Mazda mpv lx
On the 1997 Ford Aspire, the oxygen sensors are typically located in two places: one is positioned in the exhaust manifold, before the catalytic converter (upstream sensor), and the other is located after the catalytic converter (downstream sensor). These sensors monitor the oxygen levels in the exhaust gases, helping to optimize fuel efficiency and emissions control. If you're troubleshooting or replacing them, ensure you access the sensors through the engine bay and under the vehicle.
on exhaust pipe there is one right under the manifold
where is the oil pump located on 1997 ford expedition
you have 4 o2 sensors 2 up stream 2 down stream they are located in the y-pipe of your exhaust 2 before your catalyst and 2 after
Depending on the exhaust system, there will be one before and one after each catalytic converter.
There are a total of ( 4 oxygen sensors ) according to the engine wiring schematic for the 1997 Mercury Mountaineer in my Haynes repair manual ( 2 oxygen sensors are " upstream " sensors used by the PCM to adjust the air / fuel ratio of the engine ) ( 2 oxygen sensors are " downstream " sensors / catalyst monitors )
