17 Best Wideband O2 Sensor (2022 Updated)

A wideband O2 sensor is a type of oxygen sensor that is used in conjunction with a Lambda sensor to measure the oxygen content in a vehicle’s exhaust gas. The wideband O2 sensor has a much wider range than a standard O2 sensor, and can therefore more accurately measure the oxygen content of the exhaust gas.
