Where is this sensor

the Air Fuel Ratio sensor is another name for an oxygen sensor


but you must make sure you get an Air Fuel Ratio Sensor when you change it because they read differently


the air fuel ratio sensor is the front sensor and is in the manifold before the cat


the downstream sensor is a regular oxygen sensor and is after the cat
