Camaro V8-305 5.0L VIN E TBI (1989)
Oxygen Sensor: Description and Operation
Port Fuel Injection
Exhaust Oxygen Sensor (02)
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.
