What is Oxygen Sensor and What is its Damage Signs?

 

Cars have many sensor systems. The oxygen sensor is one of the most important parts of the exhaust system. The oxygen sensor is located inside the car exhaust pipe and has a large role in measuring and controlling oxygen coming out of the exhaust and provides the car's computer with this information to determine the amount of fuel needed by the engine.

 

What is the importance of oxygen sensor in the car?

 

The importance of the oxygen sensor is to monitor measure the amount of oxygen coming out of the vehicle exhaust, which is seen as an indicator of the efficiency of the system as well as the engine of the car. The ratio of oxygen discharged from the exhaust indicates the efficiency of the engine in burning the fuel and oxygen mixture.

The oxygen sensor sends this data to the engine control to adjust the amount of fuel consumption  depending on the amount of oxygen exhaled to maintain a perfect mix. The fuel ratio changes depending on the vehicle's traffic on the heights, overload, acceleration, and engine temperature.

 

What is the life expectancy of the oxygen sensor in the car?

 

In the past, oxygen sensors lasted only 60 kilometers and then needed to be replaced. At present, the oxygen sensor lasts up to 100 kilo miles or more until the sensor needs to be replaced.

 

What are the signs of oxygen sensor damage in the car?

 

1. The first sign of sensor damage is the check engine light being on.

2. Poor performance and poor fuel consumption.

3 - Difficulty operating the car, or heavy operation of the car.

What are the causes of a damaged oxygen sensor in the car?

 

Although the life span is somewhat long but there are many factors that can lead to faster sensor damage, including:

 

1- Use of contaminated or mixed fuel.

2 - Burning fuel leaving carbon deposits on the sensor.

3-  External pollution, chemicals, sand or road dust, materials used in road construction.

4 - The lifespan of the sensor has expired.
