5.6 O2 Monitor Test
EOBD regulations set by SAE require that relevant vehicles
monitor and tests on the oxygen sensors to identify problems
related to fuel efficiency and vehicle emissions. These tests are not
on-demand tests and they are done automatically when engine
operating conditions are within specified limits. These test results
are saved in the on-board computer's memory.
The Oxygen 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.
The Oxygen Monitor Test function is not supported by vehicles which
communicate using a controller area network (CAN). For Oxygen
Monitor Test results of CAN-equipped vehicles, see 5.7
"On-Board Monitor Test".
