Smog Check

[356to966]

My California 02 996 wouldn’t  pass the smog check because the tech got a 
“ monitors were not ready” signal. I’ve tried to run the prescribed adaptive drive cycle. (What a pain that is.)

Now I’m wondering whether my Durametric software will tell me if my PMC has reset and I can try the smog test again. 
Thanks for any input.

The simple  answer is yes, Durametric will tell you the status of the smog monitors.  Sometimes it works better to disconnect the negative battery lead, wait 20 minutes, re-connect then do the 30-60 minutes of drive time to re-establish all the ECU/DME monitors.  There are some detailed threads on what other people did regarding the drive time and getting all the smog monitors good to go.

First of all, the 2000 - 2002 cars are well known for requiring long drive cycles before resetting the I/M Readiness monitors, having to drive 200 or more miles is common.

 

Second, disconnecting the battery will take you back to zero; the monitors in question will have to start all over again if you do that.

I can confirm what JFP says.  It’s been many years but I recall very clearly on a 2002 911 C4S after replacing cats/o2s having to drive many miles until the readiness state would go to OK (and I could go get my emissions sticker).  Durametric will only tell you the status of the states; it can not speed up the process of resetting/correcting the readiness states.

I found that I had to drive around with RPM below 3k to get my 2004 to set all ready.
