I have a 2007 Mercury Milan - 3.0 V6
Recently replaced cat and cleared P0420 Cat Efficiency Below Threshold Bank 1 error.
Need inspection.
How long does it take for the Readiness Monitors related to this error to reset?
Is there anything that I can do to speed the process along?
My state, Missouri, requires 1 related incomplete can remain and still pass emissions.
More that one incomplete disallows passing emissions.

 

That particular monitor will usually run with some city driving and some highway driving.Just make sure to do both for a few miles to allow the monitors to run.

Side note;
As long as certain other monitors were able to "Pass" the catalyst monitor should run without any problem.

 

The monitors can be forced to complete within 'specific' detailed drive cycles being met. Depending on your drive length/miles, conditions needed during, generally a few days +/-. That said, if a forced attempt, it helps to have a copilot reading you the drive commands or details otherwise dicey to do both. If your in a rush, I can copy the drive strategy and post it, or email it...

 

Yes, please......if you can provide the strategy....ty !!!

 

My Drive Cycle Guide doesn't cover your MY,, but I sent a Ford generic Drive Guide to your email...
