Catalyst not ready

I finally fixed my p1188 and p1189 codes, cleared it and driven my car 300 miles following the driving cycle the past few days. With my OBD tool, only the catalyst not ready still remains, the other ones set easily with the driving cycle.

Anyone got some ideas?

Will it pass smog here in Cali with the catalyst not ready?

If Cali is like VA, it will not pass without all the monitors reset. Have you driven above 60mph, and also in slow stop-and-go traffic? There was a breakdown of the driving cycle necessary to reset them posted recently.

Not correct, matter of fact I just had one of my cars pass with 1 monitor not ready in VA.

VA and I think CA and other states have a graduated rule that may allow up to 2 emissions readiness codes to not be clear as long as the CEL light is not lit.

Usually the graduated scale depends on the year of the car, older cars many times allow up to 2 emissions readiness code to not be clear.

You need to check with CA rules, I am sure any SMOG station can answer the question and/or you can search the Internet for more info.

Usually the Evap codes may be the hardest to clear. Also many cars that have had CEL on for a long period that had to do with a specific system may delay the emission readiness for that part of the system.

Catalyst readiness sometimes requires a bit of highway driving to get everything warm & stable. So if your 300 miles has been in town, you may need to get at least 30 minutes at highway speeds?

In PA you are allowed 2 not ready for 2001 and older. 2002 and up is 1 not ready. Not sure about CA.

Kind of what I expected.

Again most states have graduated Readiness Indicators that cannot be set, the oldest cars may have up to 2, slightly newer cars 1, then cars usually less than 5-8 years old need all Readiness Indicators clear or passing.

Glad you got your car to pass, chances are in the next few days your last readiness monitor will clear anyway??

Hmm, good to know. I've been trying to get the catalyst readiness monitor set on the M3 again (new battery). Took forever 2 years ago, too.
If we can get by with 1 not set, I might just try getting the smog check done now.

There can be two monitors that have not been set.

Just make sure that the number of monitors are not graduated by year. Many states allow newer cars 1 monitor not set to pass inspection, then allow older cars 2 monitors not set to pass inspection. This is true as long as the CEL is not on!

Just got back from the smog check and my 2002 M3 passed with the catalyst readiness monitor not ready (confirmed still unset when I got back).

From the CA BAR site:
Quote:
The maximum allowable readiness monitors for model year 2001 and newer vehicles is one unset monitor. Model year 2000 and older vehicles are allowed two unset monitors.
