The need for oxygen sensor in your car

The Need for Oxygen Sensor in Your Car

Cars are made of a number of working parts that are more susceptible to wear and tear.

The oxygen sensor is one such component that is least affected by the driving conditions of the car.

The O2 sensor is a tiny part of the fuel delivery system but can have a strong impact on fuel economy and the engine performance.

About an O2 sensor

The O2 sensor is an electronic chip that is used for controlling the exhaust emissions of a car.

In normal conditions, the O2 sensor comes across these two possible problematic cases: There is too little oxygen, which means the mixture is rich.

There is too much oxygen, which means the mixture is lean.

Both of these cases are trouble and in either case, you should take the car for an inspection.

The function of the O2 sensors

The oxygen sensors are a pivotal component of the engine control unit and are used to perform the following two important functions.

Catalyst performance

The oxygen sensors help to create ideal conditions for treatment of the exhaust gases in the catalytic converter.

The readings of the oxygen sensors constantly change according to the engine load, acceleration, temperature and other factors.

Fuel management

The oxygen sensors find if the engine is running a rich or lean fuel mixture by burning a portion of the oxygen as it comes through the exhaust system.

For efficient fuel management, the engine's ECU depends on the input from the oxygen sensors to control the fuel mixture

Oxygen sensors eventually need to be replaced in all vehicles.

It is good to know when your car's oxygen sensor has failed as it will save the other parts from malfunctioning.

A functioning oxygen sensor ensures that the engine is running at top performance.
