Have you ever been in a situation where you needed to have your car inspected, only to find out that some of the OBD II monitors weren’t ready? It’s a frustrating experience, especially when you don’t know what to do next. Today, we’re going to dive into the world of OBD II monitors and help you understand how to determine if they are complete.
Understanding OBD II Monitors
OBD II monitors are a crucial part of your car’s emissions system. They constantly track the performance of your vehicle and record any issues they detect. These issues are then stored in the car’s computer as diagnostic trouble codes (DTCs).
Why Are OBD II Monitors Important?
Think of OBD II monitors as your car’s health check-up. They help ensure that your vehicle is running efficiently and isn’t polluting the environment. When these monitors are complete, it means your vehicle is in top shape and has passed all the necessary checks.
Determining If Readiness Monitors Are Complete
The process of checking your OBD II monitors depends on the specific make and model of your car. You can use an OBD II scanner, which is a device that plugs into your car’s diagnostic port.
Using an OBD II Scanner
To check readiness monitors, you’ll need an OBD II scanner like the GS-911 USB OBD-II Enthusiast Version Diagnostic Tool. Plug the scanner into your car’s diagnostic port and follow the instructions provided by the manufacturer.
Interpreting the Results
The scanner will display a list of readiness monitors, each with a status of “Ready” or “Not Ready.”

Common Reasons Why Readiness Monitors Are Not Ready
Several factors can cause a monitor to be “Not Ready.” These include:
- Insufficient Driving Conditions: Some monitors require specific driving conditions to run properly. For instance, the EVAP Monitor often requires a long drive at highway speeds.
- Vehicle Malfunctions: A malfunctioning component can trigger a “Not Ready” status.
- Recent Repairs: If you’ve recently had repairs done to your car’s emissions system, the monitors may need some time to complete.
How To Get Readiness Monitors To Complete
If your OBD II monitors are not ready, you can try the following:
- Drive Your Car: Take your car on a long drive at different speeds.
- Clear Your Diagnostic Trouble Codes: Using an OBD II scanner, clear any stored codes. This can sometimes reset the monitors.
- Seek Professional Help: If you’ve tried all the steps above and the monitors are still not ready, it’s time to consult a qualified mechanic.
Additional Tips for Ensuring OBD II Monitors are Complete
- Follow Your Car’s Maintenance Schedule: Regular maintenance, such as oil changes, can help ensure your car’s emissions system is functioning properly.
- Monitor Your Check Engine Light: If the light is illuminated, it indicates a potential issue that needs to be addressed.
- Avoid Using Gas Additives: While some gas additives claim to improve fuel efficiency, they can sometimes cause issues with your car’s emissions system.
