What is a Readiness Monitor?

Readiness monitors show when the vehicles computer has self-tested the emissions control system. This self-test determines if the emissions system is working properly or not. If a number of monitors have not done the check (see below), the “Readiness Result” will be a “Fail”.

Why does a monitor report "Not Completed"?

The monitor will report "Not Completed" until the vehicle's emissions computer finishes the self-test of the monitor. The vehicle needs to be driven in a way that allows the self-test to complete.

Common reasons monitors are "Not Completed"?

  • Battery replaced or disconnected.
  • Memory cleared by a repair shop (removal of Diagnostic Trouble Codes).
  • Power or grounding issue to the vehicle's computer.
  • Requirements for emissions system testing were not met, such as operating temperatures.
  • Problem that has yet to turn on the "Check Engine" light.
  • Improperly installed aftermarket system.
  • Software update for vehicle's computer.

Why does my vehicle fail when monitors are "Not Completed"?

The readiness monitor test is a "Fail" because the vehicle's computer hasn't tested itself. The emissions test itself checks readiness monitors to determine if the vehicle's emission system is passing or failing. The vehicle will fail until the required number or types of readiness monitors are tested.

How do monitors go from "Not Completed" to "Completed"?

Driving 4-7 days in city and highway usually resets the monitors. Vehicle must meet basic operating criteria and complete its manufacturer drive cycle for a particular monitor. Check your owner's manual for drive cycle information.

What if monitors don't reset after weeks of driving?

You may need to repair your vehicle. Go to a qualified emissions technician to have them diagnose the reason. Tell them if the check engine light was on and why, and if repairs were made.

Can I get a waiver for readiness?

No, there are no waivers for readiness as per EPA guidelines.
