What are some tips for servicing an oxygen sensor on Ford Fusion?

To service an oxygen sensor, warm the engine before removal to prevent damage. Avoid harming the pigtail or electrical connector and keep contaminants away from the sensor. Do not use cleaning solvents. Handle the sensor carefully and ensure the silicone boot is correctly installed. To replace the upstream sensor, locate it, disconnect the connector, and unscrew the sensor with a wrench or sensor socket. Apply anti-seize compound to the threads if reusing. Repeat the process for the downstream sensor.

Ford Fusion Oxygen Sensors

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.
