Oxygen Sensor Symptoms

Last Updated on November 4, 2022 by SogouAuto


What Is An Oxygen Sensor?

An oxygen sensor is a device that monitors the oxygen levels in a vehicle’s exhaust system. It helps ensure that the engine is running at optimal efficiency by maintaining the correct air-fuel mixture. The oxygen sensor consists of two elements: a zirconia ceramic cell and a platinum catalyst. These materials create an electrical current that increases as the level of oxygen in the exhaust decreases.

Fixing A Bad Oxygen Sensor

If you think you have a bad oxygen sensor, the best thing to do is take it to a mechanic for diagnosis. They will be able to tell for sure if the sensor is bad and replace it if necessary. Replacing a bad oxygen sensor is fairly inexpensive and will save you money in the long run by improving your fuel economy and preventing further damage to your engine.
