How to Service the Heated Oxygen Sensors on Mercury Milan?

The first step for servicing the Heated Oxygen Sensor (HO2S) requires disconnecting the electric connector. Apply penetrating and lock lubricant to the sensor threads and use it as a helping agent during extraction. The Exhaust Gas Oxygen Sensor Socket is needed to extract the HO2S. Correctly set the torque wrench to the specified torque value then tightly fasten the sensor to 48 Nm (35 lb-ft). The HO2S threads should get a thin layer of anti-seize lubricant before the reverse installation process takes place.

The Mercury Milan Oxygen Sensors are parts that are crucial and play a massive role in the improved performance of your car. Deservedly famous for their quality, these sensors measure the remaining oxygen in exhaust gases, controlling the fuel to air ratio and emissions. Because the Mercury Milan Oxygen Sensors creates a voltage signal relative to the current concentration of oxygen, fuel injector pulse width can be adjusted by the engine control computer to accomplish the system's "closed loop" operation, thereby improving the function of the catalytic converter. Depending on the model and year of production of Mercury Milan, these sensors can be of 2006-2011 and use such technologies as zirconium dioxide; there are both narrow-band and wideband architectures that will allow for the precise control of the air-fuel ratio. The narrow-band sensors supply the rapid pulses of rich/lean information whereas a wide-band has a broader range of measurement for the optimal performance of the engine. It is important that a Mercury Milan Oxygen Sensors be checked every so often or changed as necessary since they are definitive causes for increased emissions and low fuel economy once they deteriorate. Mercury Milan is a stylish mid-size sedan which has been developed with focus on the driver and EMC (Ergonomic Man Comfort) concept. Some of the special attributes of this car are that it easy to ride and has better fuel efficiency making it popular in the automotive industry. All in all, the Mercury Milan Oxygen Sensors are crucial for more effective and secure performance of the vehicle and that's why they are considered to be one of the most important components of Mercury.
