Mercury Mountaineer Oxygen Sensor

Why you drive your Mountaineer.

Select Your VehicleWhen your Mercury Mountaineer was born, it was destined for a driver who values long-lasting quality in their automobile. You purchased your Mountaineer because its high-value and a trusted name agreed with your nature; so why would you settle for second rate when it comes to the highest quality auto parts? Obviously, you bought your Mountaineer because you understood you would be getting performance and American style both rolled up into one vehicle. The vehicle in your driveway symbolizes the best in class when it comes to all the vehicles in today's marketplace.

The function and purpose of Oxygen Sensor.

Reducing harmful emissions that come from your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Mercury Mountaineer is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Mercury Mountaineer oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.
