I was worried that I wouldn't pass, with the I/H/E and all, but i did yay! so if anyone else is worried about it you should be good

 

Pretty much as long as you have no CEL you are fine,since it is OBD tested and not sniffed anymore it just plugs in and looks for errors and if finds it fails.

 

i'm worried about this too next year when i have to do it since i have that turbo on - lets hope

 

do you have a CEL on Shawn....if so it will fail,gotta get it thinking there is nothing changed in the computer with no CEL or you will fail.

 

What if you disconnect the battery and clear any cel right before your inspection, will that work?

 

Yes my CEL is on, along with my traction light & my vlc light as well. i have had it tested & it is my rear O2 sensor making it trip.

Fokai, if i do unplug my battery for 15 min or so then it will reset it and work just fine for awhile before coming back on again

 

So once cleared by battery reset, will that trick the inspection and result in a PASS?

 

According to "rumor" th full reset to "clear" status will not be reached until all parameters have been checked, and if the "clear" status is not set, it is a fail.

If the O2 sensor fails to pass tests, it will cause one or more codes, if it has not yet been tested, the "clear" status will not be set...fail.

Just sayin'

 

Ahh ok. So i'm assuming a scangauge can't reset it either?

 

i hope i can trick it - we'll see in 2011 when i have to get my 1st emissions

 

OK, Tried three time to post a reply from my cellphone, and didn't make it...

Back on my laptop so here it is...

A Scangauge II will reset the ECU and the code it was throwing will "go away."

This does NOT mean that the vehicle will pass an emissions test.

Why is this? First thing a legit emissions test checks is if the ECU has completed all the required tests.

If any of the tests have not been completed, it should show a failure.

When one "resets" a code, the ECU will begin running it's tests of that component. Some of these tests are quite involved and can require several complete "trips" from cost start through idle to operating temperature and running through all normal load criteria.

Many times "resetting" a code either by pulling the fuse , removing the battery, or using an external device WILL cause the light to go out, and it may not return for several days. This does not mean that the ECU shows the component as "clear," only that it has not completed all the tests.

If a code keeps coming back after being reset, it is likely a legit code and will show either "incomplete" or "failed" during an emission test, and neither of those is a "Pass."

Check the Scion Docs link in my signature - the OBDII .PDF that includes the Toyota codes has a good writeup of how the OBDII works, and goes into much more detail about taking a long time to complete some tests.

See this link for an explanation of the state printout - http://www.emissiontestwa.com/testre...planation.aspx - and note that Washington state will "fail" a vehicle if the ECU has not completed it's tests and does not report "readiness" (but you can come back and re-test after the ECU has completed it's tests).

If you want to go through the step-by-step tutorial from the state, you can do that here: http://www.emissiontestwa.com/testre...planation.aspx

Hope that helps.

 

yep once the light goes out the computer starts retesting again,and if the car is in state of retesting it will register as fail on the OBD testing by emissions.

 

ok help out the retarded kid here what the HECK is a CEL

 

CEL = Check Engine Light

The Malfunction Indicator Light, or MIL is another name.

Whatever it's called it's the light that comes on when your ECU has a gripe about something.

 

Great explanation Tomas, now i know thanks

 

THE ONE THAT COMES ON EVERY 5000 miles?

 

 

Once again MR. Tomas

Thank you

 

NO! Thats the Maintenance Req light.
