Oxygen Sensor Some vehicles have (2 ) or (4) O2 sensors. If you look inside the engine compartment right on the manifold is one O2 sensor, the other is underneath the vehicle about half way back in relation to the catalytic converter. If you see where the exhaust joints together.
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 Sometimes it will take 15 minutes or take a few hours it depends on your luck...
