The Oxygen Sensor in GMC Envoy vehicles helps in determining the amount of air and fuel mixture that is perfect for the vehicle engine exhaust for efficient running the vehicle and also to minimize emission. Through comparing the concentration of oxygen in exhaust with that of the surrounding environment, such as air, it produces a voltage-signal that reflects the condition of the mixture as either rich or lean. This feedback enables the engine control computer to vary the fueling signal to the fuel injectors appropriately so that maximum catalytic converter activity and least emissions are maintained. The GMC Envoy automobiles generally have a minimum of 2 oxygen sensors, the prior to the catalytic converter one and the following one, to the catalytic converter where the upstream oxygen sensor is the main feedback giving tool. The high temperature sensor has the drawback of degradating with age by contamination and thus leads to high emissions and low fuel consumption. In some newly manufactured cars, it is difficult to obtain an air / fuel ratio sensor rather than an oxygen sensor as the latter has a broader range of air / fuel measurement mixture.
