Air Fuel Ratio Sensor
An air/fuel ratio sensor is much like an oxygen sensor, or O2 sensor, and is slowly replacing them on many vehicles. Especially today's more sensitive, turbocharged, and efficient engines. Unlike the vulnerable O2 sensor, an air/fuel ratio sensor is a wide range sensor rather than narrow range, and it operates by conduction rather than generation and is therefore slightly more accurate.
