Does anyone know how to check if the system monitors have reset. Cant get car smogged due to evap system monitor not ready. I cleared the computer last friday, went to smog monday and was told monitors not ready. Its now thursday. Im assuming it should be ready by now but is there a way i can check this myself before going back to smog?

 

The only way I know of is to check the systems with a Tech 2 scanner. There is a function that can be selected that will list each monitor (module) and report back as "OK" or "Not Ready".
Most systems reset fairly soon after a reset, but some things like EVAP and Catalyst take longer. I don't know exactly how long it takes, but it's a combination of start ups, and miles ran before everything resets. I want to say 3 starts and 50 or 100 miles for most things, but I think the EVAP system takes around 100, and catalytic converter takes 500 miles.

 

@plumbob
Ya, i talked to a few people who also said the evap monitor takes longer.
Theres nowhere that offers free testing/scanning with Tech II scanners is there? Id have to know somebody who owns one or buy one myself huh? Lol

 

Ya nothing comes for free in this world anymore. I have my own and know there are other individuals that do too, or you could call around and find a shop that has one.

 

Some OBD2 scanners actually show the ready states too. You can try autozone or something local and see.

 

I use a cheap bluetooth ODBII tool paired to my laptop and I use a program called ScanXL-pro I bought years ago. There are probably a bunch of tools that can check those monitors, but it would take some research to learn which ones.
