What is a Wideband O2 Sensor?


A wideband oxygen sensor, also known as a lambda sensor, measures the amount of oxygen in the exhaust gasses of an internal combustion engine. These sensors are designed to provide a more detailed range of information than a traditional narrow-band oxygen sensor, which primarily only indicates whether the mixture is rich or lean. A wideband oxygen sensor provides a more precise measurement of the air and fuel ratio in the exhaust, enabling the engine control unit (ECU) to make finer adjustments to optimize engine performance, fuel economy, and emissions. This is particularly useful when more controlled customization or optimization of the fuel mixture is desired such as in modern engines with advanced fuel injection systems, turbochargers, and catalytic converters, as it helps maintain the engine in its optimal operating range. When upgrading to a wideband or performance oxygen sensor, shop O'Reilly Auto Parts, where we carry a selection of wideband oxygen sensor kits, cold air intakes, and other accessories needed for upgraded performance.
