How to Service the Heated Oxygen Sensor on Ford Fusion?

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 Oxygen Sensor of a Ford Fusion checks the oxygen in the exhaust fumes and compares it to outside air. It sends a voltage signal back to the engine control computer. Inside a ceramic body protected by a threaded steel shell mounted on the Fusion exhaust, the Oxygen Sensor has a zirconium dioxide element that is coated with platinum electrodes and has slots exposing the tip to hot gases. Ford incorporates a built-in heater on many of its models which heats up the Oxygen Sensor to approximately 600°F in no time so that the system can go into closed loop. In a closed loop system, the pulse width of the injector is varied constantly so that the mixtures are balanced. As a result, a good catalytic conversion takes place and very few emissions are produced. A typical Ford Fusion has at least two Oxygen Sensors installed. The upstream Oxygen Sensor monitors the air-fuel ratio and sends the appropriate signal to the computer. The downstream Oxygen Sensor measures the performance of the catalytic converter. The upstream sensor voltage changes between approximately 0.1V (lean) and 0.9V (rich). The computer monitors and adjusts the fuel delivery several times a second. When any Ford Fusion Oxygen Sensor either deteriorates or becomes contaminated, it can either slow down response or stop output. This can result in increased emissions and diagnostic trouble codes that turn on the check engine light.
