Oxygen Sensor: Description and Operation
Description
This sensor is located in the exhaust manifold and provides a voltage (in millivolts) for the microprocessor that is proportional to the oxygen
content in the exhaust gas.
A lean air/fuel mixture causes the exhaust gas to have a greater oxygen content. A rich air/fuel mixture causes the exhaust gas to have less oxygen
content.
