When it comes to your car, you know that engine performance is of the utmost importance. You want great engine function from top to bottom. Your engine, however, is not an island: it depends on all your car’s other systems in order to function properly and smoothly.

In particular, your engine system is highly dependant on the exhaust system of your Subaru Outback. You simply can’t get top engine performance with a sub-par exhaust system.

The major link between these two systems is your Subaru Outback Oxygen Sensor – and, because it directly affects the way your exhaust and engine systems interact, it is an incredibly important part of the way your car runs. Your oxygen sensor is located near the end of your car’s exhaust system. Here, it is responsible for measuring the amount of oxygen present in your exhaust vapors. What does this have to do with anything? Simple. Your internal combustion engine relies on a combination of air and fuel in order to function properly. You need to provide your engine with the optimum fuel-air mixture in order to ensure great efficiency and great function. This fuel-air mixture is controlled and provided by your car’s fuel injection system. Your fuel injector, however, must first gather information about what the appropriate fuel-air mixture might be – and it uses the oxygen data from the Subaru Outback Oxygen Sensor to do just that. Without a great oxygen sensor, then, it is impossible for your fuel injector to provide your engine with the optimum fuel-air mix and for your engine to run as efficiently as possible.
