Custom Cruiser RWD V8-350 5.7L (1992)
Oxygen Sensor: Description and Operation
Oxygen Sensor
The oxygen sensor is located in the exhaust system. The sensor monitors atmospheric air versus exhaust gas oxygen content to produce a voltage output.
This voltage ranges from approximately 0.1 volt (high oxygen - lean mixture) to 0.9 volt (low oxygen - rich mixture). By monitoring the oxygen sensor
output voltage, the computer can determine the amount of oxygen in the exhaust gas and adjust the air/fuel mixture accordingly.
