Understanding Oxygen Sensors: Key to Efficient and Clean Engine Performance

Oxygen sensors are vital components in modern vehicles, ensuring efficient engine performance and reduced emissions. These sensors monitor the amount of oxygen in the exhaust gases, allowing the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion.

What is an Oxygen Sensor?

An oxygen sensor, also known as an O2 sensor or lambda sensor, measures the oxygen levels in the exhaust gases of an internal combustion engine. This information is crucial for the ECU to adjust the air-fuel ratio, ensuring that the engine runs efficiently and produces minimal emissions. Modern vehicles typically have multiple oxygen sensors placed before and after the catalytic converter.
