OBD II regulations require applicable vehicles monitor and test oxygen (O2) sensors to determine problems related to fuel and emissions. The O2 Monitor Test allows retrieval of 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. O2 sensors are tested when engine operating conditions are within specified limits.

✓If the vehicle communicates using a controller area network (CAN), O2 monitor tests are not supported by vehicle. A message is displayed. See “Diagnostic Monitor Tests” on page 4-30 to see O2 monitor data.
