The oxygen sensors are the sensors generating an electric signal according to the ratio between the oxygen inside
the exhaust gas and the oxygen inside the outside air. By means of these sensors it is possible to measure the deviation from the stoichiometric ratio (lambda ratio) of the air – fuel mixture sent to the cylinders.A. Pre-catalyst oxygen sensor (LINEAR)

• The coatings act as electrodes.
• One layer of electrodes is in contact with external air, the other with the exhaust gases.
• The difference between the oxygen contained in the outside air and that in the exhaust gases generates the
sensor’s voltage.
