O2 Sensors

Automotive oxygen sensors—better known as O2 sensors–make modern electronic fuel injection and emission control possible. They help determine, in real time, if the air–fuel ratio of a combustion engine is rich or lean. Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine.

When an O2 sensor fails, you’ll be heading our way to pick up the proper replacement part—we’ll be ready for you!
