How to Service the Heated Oxygen Sensor on Ford Expedition?

The service process for Heated Oxygen Sensor (HO2S) requires positioning the vehicle on a hoist at neutral. Remove the HO2S by using the Exhaust Gas Oxygen Sensor Socket while disconnecting its electrical connector and apply penetrating lubricant to aid the removal process. When installing the new HO2S you should apply high temperature nickel anti-seize lubricant to its threads using a light coat. The correct torque setting for the HO2S installation must be determined followed by tightening the sensor to 46 Nm (34 lb-ft) with the Exhaust Gas Oxygen Sensor Socket. Finally, reconnect the HO2S electrical connector.

Ford Expedition Oxygen Sensor aids in determining the ratio of unburned oxygen present in the exhaust. In addition, it transforms the variance between the outside air and exhaust gas into a voltage signal that assists the Ford engine control computer in maintaining an ideal air fuel mixture. The sensing element, which is made of zirconium dioxide, has its electrodes coated in platinum and is built into a ceramic body, all of which is protected by a screw-threaded steel shell having side openings that allow the tip to be exposed to exhaust, while the top ports admit outside air. The built-in heater heats the unit closer to 600°F, and the closed loop control starts sooner. The Oxygen Sensor generates voltage in the 0.1V to 0.9V range. These adjustments generate various signals in the computer that will adjust injector pulse width several times a second. Every design of Ford Expedition has at least two sensors, but V8 versions have four to enable the upstream units to regulate the mixture and the downstream ones to verify the efficiency of the catalytic converter. The computer of the Expedition will lock into a rich setting that raises emissions if one Oxygen Sensor starts to slow down or fails to work. Every Oxygen Sensor continuously feedback the system. Oxygen Sensor response time can be confirmed by periodic checks to keep your Ford Expedition clean and conserve fuel.
