The Oxygen Sensor involved in Chevrolet Equinox is the system that adjusts the air/fuel mixture of the engine exhaust in order to achieve better performance along with less pollution. The sensor measures the amount of unburned oxygen and through comparing it to the amount of oxygen in the atmosphere, creates an electric signal that the engine control computer takes and uses to correct the fuel injector pulse width. Having a zirconium dioxide sensing element with platinum coating, the sensor works at high temperatures, switches between the rich and lean conditions to ensure the effectiveness of catalytic converters. Chevrolet Equinox vehicles normally require at least 2 oxygen sensors, one ahead of the catalytic converter and the other after it though the ahead sensor provides most of the feedback. Like the other oxygen sensors that give rich/lean signals, newer cars may come with wideband air/fuel ratio sensors. Impurities such as silicates and phosphorus reduce the efficiency of the sensors, and this indicates more emission and less fuel consumption. Maintenance and inspection of the Oxygen Sensors are critical tasks that should be carried out on Chevrole Equinox engines due to their roles in determining the correct function of the engines as well as emission control.
