Jan 15, 2013  MS3 Air Fuel Ratio (Actual Readings) I see lots of threads speculating on what it should be but for those who have gauges or a Dashhawk, what are you seeing? My command AFR is 14.6 or so at idle and at part throttle. Compare 2010 Mazda 6 Air- Fuel Ratio Sensor brands.

Air fuel ratio sensors, commonly known as a oxygen sensors, tend to fail within the driveability system of vehicles.When this sensor fails the engine will not perform optimally and can pollute the environment. Usually an engine light will come on letting the operator know that something is not functioning properly. The indicator light that is associated with an air fuel ratio sensor will.
