Should a Jeep Cherokee bad oxygen sensor be changed when the vehicle runs great with the light on or off?
It depends on whether you are in a state that requires Smog certification, and also by what you consider 'runs great'. A faulty Oxygen Sensor will never pass a Smog check, so if one is required to register the vehicle, you have no choice. Just because a vehicle seems to 'run great', doesn't mean that it actually is. I would suggest replacing the sensor as soon as your finances will allow. That sensor is an integral part of the emission system, and the emission system an integral part of the overall performance of the vehicle. Garbage in, garbage out my friend. = )

The O2 sensor is located on the exhaust, most Cherokee's have 2 exhaust banks, so there should be one on each side of the engine. Find a wrench to fit it and screw it out, there should be an electrical connection running to it so find where it connects and disconnect it. Reverse for installation.
