4.6 O2 Monitor Test
OBD II regulations require certain vehicles monitor and test oxygen (O2) sensors to isolate fuel
and emissions related faults. The O2 Monitor Test function is used to retrieve completed O2
sensors monitor test results.
The O2 Monitor Test is not an on-demand test. O2 sensors are not tested when selected via the
menu but tested when engine operating conditions are within specified limits.
If the vehicle uses a controller area network (CAN) protocol
to communicate, this function is not
supported by vehicle. Refer to “On-Board Monitor Tests” on page 38-39 for O2 monitor data of
CAN-equipped vehicles.
To retrieve O2 monitor data:
1. Use the UP/DOWN key to highlight O2 Monitor Test from Diagnostic Menu and press the
ENTER key. A screen with a list of available sensors displays.
