How to Service the Heated Oxygen Sensor on Ford Taurus?

Start the service of Heated Oxygen Sensor (HO2S) by first securing the vehicle on a hoist using neutral gear position. The electrical connector of the HO2S must be disconnected. Penetrating and lock lubricant serves to minimize resistance when removing the sensor by applying it to its threads. The Exhaust Gas Oxygen Sensor Socket enables you to remove the HO2S while following torque calculations for the specified torque level. Work through the following steps for new HO2S installation while applying light anti-seize lubrication to its threads then tight the sensor to 48 Nm (35 lb-ft). Continue by performing the removal steps in opposite order to finish the installation.

The Ford Taurus Oxygen Sensor monitors the quantity of unburned oxygen present in exhaust gases. Consequently, it transmits a voltage signal to the engine control computer for maintaining the air-fuel mixture close to the ideal level to control emissions. A zirconium dioxide element coated with platinum electrodes is enclosed in ceramic and protected by a threaded steel shell that screws into the exhaust stream. Openings let exhaust reach the tip while other vents admit outside air. When the sensor reaches roughly 600°F, the difference in oxygen content moves ions that create a voltage from about 0.1V when the mixture is lean to 0.9V when it is rich. Many late-model Ford Taurus models carry at least two units, an upstream Oxygen Sensor located before the catalytic converter provides primary feedback and a downstream Oxygen Sensor located after the converter provides a catalyst monitor. As the voltage from the Oxygen Sensor cycles, the computer is constantly adjusting the injector pulse width. This is closed loop operation. The Ford Taurus Oxygen Sensor can be slow to respond if it deteriorates or becomes contaminated. This can cause increased emissions and trigger the check engine light. The internal heater speeds warm-up to stabilize the Ford Taurus system, which allows regular function.
