An oxygen sensor is an electronic device that measures the proportion of oxygen in the gas or liquid in the car. Most vehicles since 1986 have at least one oxygen sensor, originally called Lambda Sensors, and newer vehicles often have two or more oxygen sensors.

What Is An Oxygen Sensor And How Does The Oxygen Sensor Works?

An oxygen sensor monitors the amount of oxygen (O2) in the exhaust gas. The amount of oxygen in the exhaust gas is a good indicator of engine combustion efficiency and is also the best place to monitor the air to fuel ratio.

In your car, a functioning O2 sensor ensures that your engine is running at top performance and also to produce as few emissions as possible.

The oxygen sensor is located in the exhaust manifold downpipes before the catalytic converter or between the exhaust manifolds and the catalytic converters.
