What is an Oxygen Sensor?

posted on 2/9/2017 4:24:56 AM

Q: What is an oxygen sensor? – Mr. Flemming

A: Mr. Flemming,

The oxygen sensor monitors the amount of oxygen in the exhaust. The engine computer in your vehicle can adjust the fuel-to-air mixture for maximum combustion efficiency, decreasing the mount of harmful exhaust even before it reaches the catalytic converter and muffler.
