How to Service the Heated Oxygen Sensors 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 Sensors found in Ford Fusion cars aids in conserving the air/fuel blend within the engine exhaust. An unburned oxygen sensor allows the detecting oxidized oxygen levels in the exhaust, which is vital for adjusting the catalytic converter and disabling the greater emissions. Ford Fusion Oxygen Sensors consist of a zirconium dioxide sensing element with platinum coating laminated by ceramic and having a steel casing. These sensors work at high temperatures and dynamically regulate the air/fuel mixture by the voltage signals received for the optimal performance. Late model Ford Fusion cars have minimum of 2 oxygen sensors for the engines, 3 for V6 and 4 for V8 engines, one before the catalytic converter and the other after it. While the primary sensor is upstream of the converter which alters the air-fuel mixture with reference to voltage signals, the second sensor tracks the effectiveness of the converter. This implies a failed Oxygen Sensor can cause high emissions as well as poor fuel economy. Some newer vehicles may include air/fuel ratio sensors instead, although they provide a richer array of measurements are prone to the same kinds of failures as simple oxygen sensors.
