The engine in your Mountaineer takes a combination of fuel and air in order to function properly. The only way for your ECU to know how much fuel to feed the engine is to know how much air is already there. This means that you need to make sure your oxygen sensor is working properly. The oxygen sensor will read the amount of oxygen present and communicate to your ECU. When your oxygen sensor is bad, it can lead to problems with your engine because of not getting enough of the fuel or air that it requires.

You can find the Mountaineer oxygen sensor by Mercury at Parts Geek. We have the parts you need so you can save money. Even if you have to take the part to the mechanic for help installing, it will be cheaper than if you were to buy the part elsewhere.
