#15 of 16 EGR, Evap, Cat "Not Ready" on 2001 Taurus by bbork10002 May 29, 2009 (7:46 am)
To make a long story short, I bought an OBDII scanner recently to clear a "check engine" light that occasionally came on. I had no idea that emissions inspection uses the same OBD plug to pass or fail the car. I did not buy it to cheat inspection.   My (wife's) Taurus is up for inspection but the airbag light was on. I called my mechanic who said the airbag light being on will not cause my inspection to fail. However, he ran out of stickers.   So I called Sears Auto and asked about the airbag light being on. Sears told me yes, my car will fail inspection if the airbag light is on.   So I used my OBDII scanner hoping it would clear the airbag light. It did not. However, when I adjusted the seat, the airbag light came off. Weird but that's good.   I went in for inspection at another shop (not Sears and not my mechanic). It failed because it showed 5 sensors "not ready" including 2 for "oxygen"-something and 3 for EGR, Evap, and Cat.   My mechanic told me to drive it around for at least 30 miles mix of highway and local traffic. I ran it for 60 miles already but only the "oxygen" sensors were cleared, the other 3 -- EGR, Evap and Cat are still "not ready".   Question: I don't mind driving the car around some more. But can I use my OBDII scanner to check if the remaining 3 sensors are ready? This way, as soon as the 3 sensors are ready, I can stop driving around.   Thanks a lot!

Replying to: bbork10002 (May 29, 2009 7:46 am) Just to answer my own question, in case someone experiences the same problem:   I fixed it. I followed the instructions for evap, catalyst, and egr (my 3 "not ready" sensors) in this webpage:   http://www.obdii.com/drivecycleford.html   The idea is to drive smoothly -- no turns, no hills -- to avoid fuel sloshing around in the tank for a few miles at 55 mph within the first 30 minutes of a cold start.   Then after (or if you are still within) the 30 minutes, drive at various speeds from 25-45 with some full stops.   That's it.
