Oxygen Sensors
Car exhaust flows have oxygen sensors that detect how much unburned oxygen your engine emits. This sensor then sends voltage to your engine control unit to determine if the air-fuel mixture in your engine is too lean or rich. SubaruOnlineParts offers a quality selection of exhaust sensors for select Subaru vehicles.
Enjoy Optimal Engine Performance with Top-Quality O2 Sensors
Oxygen sensors monitor how much oxygen your exhaust stream has, and ensure that your catalytic converters are working through oxygen level checks. Exhaust sensors oxidize some oxygen as it passes through the exhaust. These auto parts then turn this reading into a voltage signal and transmit it back to your engine control unit (ECU). Once your ECU detects that the air-fuel mixture is too rich or lean, the unit will increase or decrease the amount of fuel to achieve the optimal A/F ratio.
O2 sensors can either be binary or universal sensors. Binary sensors compare the excess oxygen in your exhaust with ambient air oxygen levels. They determine when a rich air-fuel mixture gets lean and vice versa. Universal exhaust sensors have a greater measuring range than binary sensors and are compatible with both diesel and gasoline engines.
Find the Best Oxygen Sensor for Your Subaru Online
Oxygen sensors are extremely durable, but can still fail over time. Contaminated fuel, carbon deposits from an engine burning oil, and external pollutants can cause these sensors to fail. The fuel economy and overall performance of your car will also falter should your O2 sensor start to malfunction. Replace these parts whenever necessary and maintain an efficient gas mileage for your Subaru.
SubaruOnlineParts carries genuine exhaust sensors in its online catalog. These top-quality auto parts are compatible with select Subaru models. All of our sensor replacements are 100% genuine, brand new, easy to install, and sold for less than the manufacturer’s suggested retail price.
