Default Failed Inspection for monitors "Not Ready"

So i took my suby to get oil, rear diff, and manual tranny fluid replaced as well as an inspection...

The car failed the inspection cause the "Catalyst", "Evap.", and "02 Sens" Monitors came back as "Not Ready"

They asked me if i had unplugged the battery latley as this will cause you to need to cycle the car for 50-100 miles before these monitors reset to "Ready"

I havent had it unplugged but very recently i used my Actron to clear some codes... does that consitute as a reset of the entire system causing it to need to cycle again? If yes how many miles do i need to get them back to ready? If no what could be causing this issue and how can i get them back to "Ready"???

Clearing the codes probably would have done it. I did that once and it blew away my AP Realtime Map.

Try taking a long drive, then letting it idle for a couple minutes afterwards. If you search around you should be able to find the specific drive cycles that will trip the readiness monitors.

OK, is there anyway, short of returning for another inspection, to tell if they have reset to the "ready"?

I have an Actron OBD2 scanner and it tells the status of the readiness monitors. Could be that you have a cheaper model maybe.

Drive at greatly varying speeds and throttle positions is best. Find a lot of stoplights and heavy traffic . Do this after the car has fully warmed up.

Cobb AP sets the catalyst monitor to be ready. My car shows the catalyst as ready immediately after an ecu reset

...if ya got any 'wired in' rear o2 'cel fix'....THAT can cause a permanant 'not ready' condition as that is how the 'wired in' fix works to keep the check engine light OFF....the test it 'pending' all the time...so NO CEL on

Nope no fix...

I use a Cattles DP with a Invidia High Flow Catted Downpipe and borla hush catback and nothing with its configuration has changed from the last inspection in which the setup was fairly new.

Im hoping i just havent hit the proper cycle to enable the cat monitor

Those all need to be completed in order with nothing in between? that might be tricky.. ill need a road i can stop on... and vary my speed from 40 to 60 mph... will be tough to do legally

How can you idle for 1 min and then do 0-60 in 20 sec... should i pull over on the highway for a min?

And some people say to accomplish this from a cold start but i live a good 8-10 min from the highway and im not doing 60mph on these 30mph roads around my house

I failed with 3 "not Ready" but i only have one (catalyst) that is not ready right now so I should pass the OBDII test!

Thanks to kozloski on OBDII Forums

Not quite sure exactly how they do it there, but here in PA if your vehicle is older than 2000 MY, you are allowed two monitors not set, and still pass, 2001- current, are allowed one. For all of you guys with code readers.. clearing codes automatically resets ALL monitors to 'not ready' status. And the ones that are most found; evap, catalyst, and O2 sensors.. are obviously the three hardest to set.. there's really no fast and easy way to do it.

BTW, if your car has previously failed for monitor status, most OBDII emissions analyzers have a Dx mode where you can check them before actually running a test. In most states, the law is written that we must test cars 'as presented', but in a lot of cases, if we know of the previous fail, we will do this first to save ourselves, and the customer a lot of aggrivation.. it also helps to be tight with the guy doing your inspection
