Oxygen Sensor: Description and Operation
DESCRIPTION The Heated Oxygen Sensors
(HO2S) are located in the dual converter Y pipe below the exhaust manifolds.
OPERATION The heated oxygen sensors react with the oxygen in the exhaust gases and generate a voltage based on this reaction.
-
A low voltage indicates too much oxygen or a lean condition.
-
A high voltage indicates not enough oxygen or a rich condition.
