Mustang Cobra V8-281 4.6L DOHC VIN V MFI (1997)
Oxygen Sensor: Description and Operation
DESCRIPTION
There are four Heated Oxygen Sensors (HO2S):
-
two are located in the exhaust pipes below the exhaust manifold before the catalytic converters.
-
two are used as catalyst monitors behind the catalytic converters.
-
these 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.
