After fixing an emission problem and clearing the error code; the Scanner report shows the following.
Your vehicle’s condition is questionable and MAY NOT PASS an emissions test. Our system has detected that not all of your vehicle’s system self-tests (monitors) have successfully completed. We recommend that you continue to drive your vehicle for a few days to allow all system self-tests to properly run before taking an emissions test.
Any Ideas about how to have the computer complete these self-tests?

Will appreciate any suggestions/feedback.
:confused:

There is a procedure for all vehicles to reset all sensors but usually they are very complicated.. IE Drive the vehicle at 60 mph for 12 minutes and slow to a stop without pressing brake, rev engine to 3000 rpm for 10 seconds, press brake pedal 4 times, Etc... If you miss any of the steps or timings you have to start all over again...

When I reset my check engine light I just drive it on the highway a short distance and they reset... Take the car on a 20-30 minute drive on the highway and they should be set after that...

I have a 98 and reset by disconnecting both battery cables for 10 minutes then hook them back up and drove it around to let it go through the set up.
