It is a sensor 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 this sensor it is possible to measure the deviation from the stoichometric ratio (lambda ratio) of the air – fuel mixture sent to the cylinders.
Each cylinder bank has two oxygen sensors: one is installed on the exhaust gas inlet coupling in the catalytic converter of the exhaust system, the other on the converter outlet.
A. Pre-catalyst oxygen sensor (LINEAR)
B. Post-catalyst oxygen sensor (ON-OFF)
C. Catalyst

• 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.
