Your Mercury dealership isn't the only place to locate genuine or original equipment quality parts to repair your Mountaineer. Mercury car, truck, or SUV drivers have grown accustomed to a certain level of reliability when driving their Mountaineer around town.

What Oxygen Sensor does for your vehicle.

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 relies on input from the 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 it will likely be emitting an excess of hazardous exhaust.

What our company has to make it special.
