Davis Bros. Auto Supply #2: O2 Sensors and Oxygen Sensors

Drivers in Rosenberg rely on their car or truck's O2 sensor to keep the engine running efficiently. Your oxygen or O2 sensor enhances engine performance by being a part of a system that adjusts the amount of air to fuel ratio entering the engine and by first measuring the unburnt oxygen in car emissions. O2 sensors are standard for cars and trucks built after 1980. Most cars in Rosenberg have an O2 sensor that should be replaced regularly.

The O2 sensor discovers the amount of oxygen in your exhaust and informs your engine's computer to adjust the fuel to oxygen ratio to keep your engine running at peak performance. A car or truck engine that "chokes or coughs" while driving at high speeds may need a new clean O2 sensor.

Narrowband and wideband are the two most common types of O2 sensors. A narrowband O2 sensor informs the computer if your engine is running a rich or lean mixture of oxygen and fuel. A wideband sensor measures how rich or how lean the oxygen to fuel ratio is. Call Davis Bros.
