7. OBD2 and Emissions Testing

7.1 How OBD2 Relates to Emissions Testing

The OBD2 system plays a crucial role in emissions testing. During an emissions test, the testing facility will connect to your car’s OBD2 port to check for any stored diagnostic trouble codes (DTCs) related to emissions. They will also verify that the car’s emissions systems are functioning correctly.

7.2 Readiness Monitors

OBD2 systems use readiness monitors to indicate whether the car’s emissions systems have been tested and are ready for an emissions test. Common readiness monitors include:

• Catalyst Monitor: Checks the efficiency of the catalytic converter.
• Oxygen Sensor Monitor: Tests the performance of the oxygen sensors.
• EVAP System Monitor: Checks for leaks in the evaporative emissions control system.
• EGR System Monitor: Tests the functionality of the exhaust gas recirculation system.

7.3 Ensuring Your Car Passes Emissions Testing

To ensure your car passes emissions testing:

1. Check for DTCs: Use an OBD2 scanner to check for any stored DTCs. Address any issues before the test.
2. Verify Readiness Monitors: Ensure that all readiness monitors are set to “Ready” or “Complete.” If any monitors are not ready, you may need to drive the car for a certain period of time to allow the system to complete the testing process.
3. Perform a Drive Cycle: If necessary, perform a drive cycle to reset the readiness monitors. A drive cycle involves driving the car in a specific pattern that allows the OBD2 system to test all of the emissions systems.

7.4 What to Do If Your Car Fails

If your car fails an emissions test, you will need to address the issues that caused the failure and then have the car retested. Common reasons for failing an emissions test include:

• Stored DTCs: Any stored DTCs related to emissions will cause the car to fail.
• Not Ready Monitors: If any readiness monitors are not set to “Ready,” the car will fail.
• High Emissions Readings: If the car’s emissions readings exceed the allowable limits, it will fail.
