The GM part 19178939 Oxygen Sensor serves vital functions for exhaust system oxygen monitoring through its three sensor distribution within the exhaust system to feed essential data to the engine control module (ECM). The exhaust system oxygen levels determine millivoltage outputs between 100 to 900 millivolts from the two upstream sensors at the front and rear manifolds and the downstream probe that sits behind the catalytic converter. The ECM needs this information to modify airflow through the system until the correct 14.7:1 air to fuel balance is achieved thus optimizing catalytic converter functionality and reducing environmental pollutants. The GM part 19178939 requires proper maintenance because contaminants must be kept away and the silicone boot must be installed correctly to avoid physical distortion. Physical stress to the component during handling should be minimized because it might cause damage that slows down operation. The sensor operates optimal when electrical wiring and correct temperature levels are maintained for continuous smooth operation. Real GM branded components maintain factory-level design specifications which leads to high standards of performance quality.
