What is the function of the front oxygen sensor?
1 Answers
The function of the front oxygen sensor is to detect the oxygen content in the exhaust gas produced after the combustion of the cylinder mixture. Generally, a high oxygen content indicates a lean mixture, while a low oxygen content indicates a rich mixture. The front oxygen sensor transmits different electrical signals to the ECU based on the varying oxygen levels, allowing the ECU to adjust the mixture accordingly. Oxygen sensors are widely used in industries such as petroleum, chemical, coal, metallurgy, papermaking, firefighting, municipal, pharmaceutical, automotive, and gas emission monitoring. In engines equipped with three-way catalytic converters to reduce exhaust pollution, the oxygen sensor is an essential component.
