Chevrolet Astro Oxygen Sensor
The Oxygen Sensor in automobiles particularly Chevrolet Astro is essentially used to check the residual unburned oxygen in the exhaust gas that is very useful to determine the mixture of air and fuel as well as generic emissions. It produces a voltage signal proportional to the concentration of oxygen, therefore the engine control computer is in a position to change the pulse width of the fuel injector. This back feedback system makes the engine to run in a "closed loop" improving the efficiency of the catalytic converter. Chevrolet Astro cars might have zirconium dioxide oxygen sensors, both narrow-band and wideband sensors are possible. Narrow-band sensors deliver repeatedly shifting rich/lean signals, while wide-band sensors supply a wider air-fuel mixture range signals. These sensors can, however, reduce in their effectiveness over time because of contaminant which causes excess emissions and less fuel economy. A Chevrolet Astro's Oxygen Sensor should be checked and serviced as often as possible for the vehicle to operate optimally.
