O2 Monitor Test
OBD II regulations set by the (Society of Automotive Engineers) SAE
require vehicles monitors and tests on the oxygen (O2) sensors to identify
problems related to fuel efficiency and vehicle emissions. These tests are
done automatically when engine operating conditions are within specified
limits. These test results are saved in the vehicle’s on-board computer's
memory.
The O2 Monitor Test function allows retrieval and viewing of O2 sensor
monitor test results for the most recently performed tests from the vehicle's
on-board computer.
