O2 Sensor Test
OBD2 regulations require that applicable vehicles monitor and test operation
of the oxygen (O2) sensors to identify problems that can affect fuel
efficiency and vehicle emissions. These tests are performed automatically
when engine operating conditions are within predefined limits. Results of
these tests are stored in the on-board computer's memory.
The
O2 Sensor Test
function lets you retrieve and view O2 sensor
monitor test results for the most recently completed tests from your
vehicle's on-board computer.
The scan tool does not perform O2 sensor tests, but retrieves
results from the most recently performed O2 sensor tests from
the on-board computer's memory. You may retrieve O2 sensor
test results for only one test of one sensor at any given time.
