Pontiac G5 Oxygen Sensor
About oxygen sensor
Oxygen sensor is an electronically controlled device, mainly used to maintain a good fuel and air mixture balance that makes the vehicle greener and more efficient.
How oxygen sensor Works?
In the presence of oxygen gasoline burns in the engine and the oxygen sensors main objective is to find out the perfect mixture of both air and gasoline. A particular ratio of air and fuel is called stoichiometric, which is the ideal ratio and is close to 14.7:1, if there is less air in that ratio then after combustion there is fuel left over. This is called a rich mixture (unburnt fuel pollutes the air). If there is excess air in this perfect ratio, this is called lean mixture (reduces efficiency and power), the oxygen sensor is placed in the exhaust pipe and can sense the quantity and quality of air and fuel mixtures or simply detect lean and rich mixtures due to excess oxygen or lack of oxygen. Oxygen sensors involve a chemical reaction capable of generating a voltage based on the voltage identity it can detect or adjust the flow of fluid that enters the engine.
Where is oxygen sensor Located?
The oxygen sensor is located in the exhaust pipes for easy air- and fuel mixture calculation.
