How Should Special Care Be Taken When Servicing an Oxygen Sensor on Subaru Outback?

For turbo models, disconnect the battery, detach the sensor harness clips, loosen the wheel lug nuts, remove the wheel, unscrew the sensor, and apply an anti-seize to the sensor threads. For the downstream sensor, disconnect the sensor, apply an anti-seize compound to the sensor threads, and reverse the procedure for installation.

Subaru Outback Oxygen Sensor

The Oxygen Sensor in Subaru Outback cars is used to find and regulate the air/fuel mixture in the engine exhaust with the optimal ratio for performance and low emissions. The mixture control is done by the sensor that compares the unburned oxygen and the atmospheric level by generating a voltage signal that enables the engine control computer to make the right decision. This feedback loop runs in what is known as the "closed - loop" mode for proper efficiency of the catalytic converter and reduced emissions. Main oxygen sensors are usually two: before and after the catalytic converter, while the former is the main feedback one. The battery of the sensor is constructed of zirconium dioxide covered with platinum and placed in the steel casing; thus, measurements of rich and lean conditions are possible to help adjust the air-fuel mixture. However, in more modern Outback vehicles, one may find air/fuel ratio sensors used to give broader range measurements In addition, both circumstances contribute to the vehicle emitting more and working less efficiently due to contamination and the general aging of the said sensors. This is so since the effectiveness of the Subaru Outback vehicle in the provision of efficiency in the engine and in the low emission control would depend on the maintenance and monitoring of the oxygen sensor.
