 Hummer  Oxygen Sensor
Hummer Oxygen Sensor

The Hummer Oxygen Sensor is an electronic device that is part of your car's emission control system. Its primary function is to help determine the right amount of fuel to be injected into the car's engine. For an engine to run efficiently, the fuel-air ratio should be perfect. If the ratio is either less (rich) or more (lean) than the “perfect” ratio, it would result in an emission of pollutants and damage the car's engine. The sensor, thus, helps maintain the car's fuel-air ratio by measuring the difference in the oxygen content of the exhaust and the external atmosphere. The difference in oxygen content is used to generate a signal that is fed to the car's engine control unit (ECU). Through this signal, the ECU determines the amount of fuel that should enter the car's engine.

A faulty oxygen sensor could eventually damage your car's engine if it is not replaced at the earliest. If you are looking for a high quality replacement for your Hummer Oxygen Sensor, you have come to the right place.
