Assuming you are replacing it with a new one, cut the wires off at the sensor and slip a 6 point 7/8" box wrench over the sensor, that should give you a good grip on the sensor.
O2 Sensor Stuck Lean (Bank1 Sensor1).
O2 Sensor stuck lean bank 2, sensor 2.
That means that your o2 sensor is stuck lean (bank 1 sensor 1)
Good Chance this is caused by a faulty O2 Sensor. I had the engine light stuck on in my 2002 Montana and replaced rear O2 sensor and it turned it off.
Trouble code P2270 means: O2 sensor signal stuck lean bank 1 sensor 2
Depends on what the problem is or what code was set.
the exhaust, where every o2 sensor is
The O2 sensor can be found on the outside of the air cleaner housing. The O2 sensor will be attached to the back of the air cleaner housing.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter

Most of the time it is just: remove the connection to the O2 sensor, screw out the old O2 sensor, screw in the NEW O2 sensor, re-make connection to the O2 sensor. Note that some O2 sensors do not have plugs and you have to cut the wire and use crimp connectors to attach the new O2 sensor. If yours has a plug, you're in luck. Note that if the package includes a tube of silicone grease, make certain that you use it to protect the connections from corrosion. One of the hardest problems is taking out the old O^2 sensor. They have been in so long that they sometimes become seized in the port. You might have to resort to penetrating oil, heating torch, or a long bar & muscle to get the sensor out. The new sensor should have a little anti-seize on the threads to prevent getting stuck in the port.
