Mazda 3 Oxygen Sensor

Why you drive your 3.

Your Mazda dealership isn't the only place to locate trusted repair parts to fix your 3. You bought your 3 because its best-in-class value and long-lasting quality agreed with your nature; so why would you be okay with anything but the best when it comes to the highest quality auto parts? Mazda vehicle drivers have become used to a certain level of fuel efficiency when driving their 3 around town. It's not a regular occurrence that you realize that you have to buy a replacement Oxygen Sensor for your car or truck.

What Oxygen Sensor does for your vehicle.

Achieving maximum power and fuel efficiency with your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Mazda 3 is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Mazda 3 oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and it will likely be emitting an excess of hazardous exhaust.

We've got what you are looking for.
