Mazda RX-7 Oxygen Sensor

Your RX-7 is a prized possession.

When your Mazda RX-7 left the factory, it was destined for a person with discerning taste who prioritizes economical pricing in their automobile. Your Mazda dealership isn't the only place to buy the best repair parts to fix your RX-7. Car aficionados appreciate the dependability built into each Mazda, and understand that only the best replacement RX-7 parts will suffice when your car or truck needs fixing. It's not a regular occurrence that you discover you need a replacement Oxygen Sensor for your automobile.

The function and purpose of Oxygen Sensor.

Achieving maximum power and fuel efficiency with your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Mazda RX-7 is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Mazda RX-7 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.
