Understanding Oxygen Sensors: Key to Efficient Engine Performance

In the world of automotive engineering, oxygen sensors play a crucial role in ensuring your vehicle runs efficiently and cleanly. These small but vital components are integral to your car’s exhaust and emission system, directly affecting fuel economy and overall performance.

What is an Oxygen Sensor?

An oxygen sensor, often referred to as an O2 sensor, is a device that measures the proportion of oxygen in the exhaust gases of an internal combustion engine. Modern vehicles typically have multiple oxygen sensors, both upstream (before the catalytic converter) and downstream (after the catalytic converter), to monitor the efficiency of the engine and the catalytic converter.
