Eagle L4-150 2.5L (1983)
Oxygen Sensor: Description and Operation
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.
