Mercury Grand Marquis Oxygen Sensors

The Mercury Grand Marquis is well known to possess considerable reliability and performance and the Oxygen Sensors is a vital factor for it. These sensors are particularly useful in the measurement of unburned oxygen in the exhaust system of the engine and the feedback is given to the engine control computer. The Mercury Grand Marquis Oxygen Sensors produce a voltage signal proportional to the concentration of oxygen, therefore aiding in the improvement of the airclock ratio for combustion, effectiveness of catalytic converter and limitation of polluting emissions. These Oxygen Sensors apply to diverse Grand Marquis models that Ornelas produced from 1975-2011 to guarantee the operation of the vehicle to the maximum efficiency and safety levels. Usually the Grand Marquis has several sensors installed - upstream and downstream ones, which control both the combustion process and the efficiency of the catalytic converter. The initial Zirconia based Sensors have a high operating temperature and faster activation and the latest models may have enhanced Air Fuel Ratio Sensors of this kind. Oxygen Sensors like any other parts are also subjected to the natural firemanship hence making it important for replacements probably after some few years of usage. The automobile market can distinguish Mercury Grand Marquis models by their luxurious equipment and powerful V8 engines as well as concentration on the car performance enhancements, especially regarding the Oxygen Sensors contribution to the car overall performance and safety.
