O2 Sensor Test<br />
OBD2 regulations require that applicable vehicles monitor and test operation<br />
of the oxygen (O2) sensors to identify problems that can affect fuel<br />
efficiency and vehicle emissions. These tests are performed automatically<br />
when engine operating conditions are within predefined limits. Results of<br />
these tests are stored in the on-board computer's memory.<br />
The O2 Sensor Test function lets you retrieve and view O2 sensor<br />
monitor test results for the most recently completed tests from your<br />
vehicle's on-board computer.<br />
Vehicles are equipped with multiple O2 sensors. O2 sensors are<br />
installed both upstream of (before) and downstream of (after) the<br />
exhaust system Catalytic Converters. The name of an O2 sensor<br />
identifies its location in the exhaust system. The name of each O2<br />
sensor is made up of three parts:<br />
O2S XX YY -or- O2S X Y<br />
• O2S - this is the basic designation for all O2 sensors.<br />
