The function and purpose of Oxygen Sensor.

Achieving maximum power and fuel efficiency with your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your GMC Sierra 3500 is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your GMC Sierra 3500 oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and emissions from your tailpipe may be in excess of legal levels.
