What's An O2 Sensor

Properly operating Oxygen sensors are an salient stuff of reducing your emissions.

The O2 (Oxygen) sensor is a crucial Element in a vehivle's emission bridle development. It is one of the many sensors that the personal computer relies upon to dispose the operating contingency of the motorcar and to produce fixed adjustments for pinnacle performance.

The Function of the O2 Sensor

The O2 sensor generates a small electric current when it is heated. The amount of current produced is directly attributable to the amount of oxygen found in the exhaust gasses. The change in voltage is the message sent to the car's computer.

The Effects of the Sensor's Messages

The computer controlling the engine will adjust the fuel mixture and ignition timing based upon the measurements it receives from the O2 sensor. As the adjustment is made, the O2 sensor reads the results of the change in the exhaust stream and returns the new measurements. This closed-loop system is constantly adjusting the mixture, so that your car runs at its best.

How the O2 Sensor Works

The sensor examines the exhaust gasses emitted by your engine and gauges the extent of O2 they embrace. Whether the gasses comprehend a gigantic percentage of oxygen, the engine is running lean. If the percentage is low, the engine is running rich.
