The O2 sensor for Subaru Outback is part of the emissions system, responsible for feeding data about the air/fuel mixture to the engine management computer. It detects whether the engine is running too lean or too rich and adjusts the fuel accordingly. When the sensor fails, your vehicle loses efficiency because the system has to guess how much fuel to use. Replace your O2 sensor when the engine light comes on to prevent stalling out and using too much gas.
