What is the Function of the Oxygen Sensor?

Oxygen Sensors are mounted on the engine exhaust manifold, sniffing exhaust gases to measure the amount of unburned oxygen in the exhaust gases and by the ECU.
It indicates that the air-fuel mixture is very poor or rich by producing a readable voltage. In this way, optimum performance and fuel economy are ensured by keeping the air-fuel mixture under control in every driving condition of the vehicle.
Description of Oxygen Sensor Faults.
The fault definition of a part that is so closely related to the performance of the vehicle is relatively easy. Many vehicles have an oxygen sensor malfunction lamp. At the same time, the driver complains of excess fuel consumption. Faulty Oxygen Sensor causes fuel consumption to increase up to 30%. Reduced driving comfort and burning losses are classic Oxygen Sensor malfunction symptoms, all of which can be eliminated by installing a suitable Oxygen Sensor in the vehicle.

Sensor Failure Problems.

* Decreased vehicle performance
* Excessive fuel consumption
* Catalytic inverter overheating and malfunction.

Maintenance and Service.
The new environmental protection laws made it compulsory to use catalytic converters in vehicles and to pass emission tests once a year. One of the primary causes of a failed engine and exhaust emission test is a malfunctioning Oxygen Sensor. For this reason, Oxygen Sensors every 30.000 km. should also be checked once. Never avoid replacing the Oxygen Sensor when you experience one of the above mentioned faults in your vehicle.
