5.6 O2 Monitor Test

OBD2 regulations set by SAE require that relevant vehicles

monitor and tests on the oxygen (O2) 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 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.

The O2 Monitor Test function is not supported by vehicles which

communicate using a controller area network (CAN). For O2

Monitor Test results of CAN-equipped vehicles, see chapter

“On-Board Mon. Test”.

2) Wait a few seconds while the scan tool validates the PID MAP.

3) Use the UP/DOWN scroll button to select O2 sensor from O2

Monitor Test menu and press OK button. (Figure 5.23)
