How long do dynamometer emissions tests usually take these days? I remember them taking about 2.5 minutes, but when I went in for the emissions test today, it took about 5 and it seemed like the technician did the test twice.
Less than 5 when they start to when they pull your car out.
They used to do those in IL with the sniffers on the tail pipe. They ended up doing away with them and only did the ODBII plug for '96 later cars.
They would drive at local street speeds and up to maybe 55mph to simulate interstate speeds.
It was a painless process if you went to the right station. Go to one where the guy would otherwise be dressed as the Statue of Liberty during tax season and it makes for a stupid experience.
it depends. if you can keep a proper constant speed, and if the car isnt borderline failing, then it should only take a minute or so.
Does the technician know on his screen when he's driving the car on the dynamometer if the car is failing or does he only know like me at the very end when the sheet prints out?
The engine must be up to temp and tests usually require steady operation at specified rpm. If you or the operator have trouble doing that it can take more than five minutes. I the car fails they make several tries.
my old 1992 Tercel failed most of the emissions tests between 2004 and 2010. the last year i had it 2011 it actually passed cos i replaced most of the exhaust system. i had a mechanic who knew exactly what to do to get it to pass all those years. cost me $80-100 more for labor but it was worth it
WOW I'm surprised to hear they are still doing those types of emission testing. Here in IL we had the Roller testing for a couple o f years then it quietly went away.
Lawsuits later surfaced where the state had paid millions of dollars in repairs to damaged cars before scrapping the entire plan and going to the OBD2 port reading.
I remember a case where one of the AWD super cars, I believe it was a Diablo had to be returned to Italy for service after a tech destroyed the transmission attempting to test it with only the rear tires on the rollers. There were countless Stealths and 3000 GT's that died at the hands of these idiots as well.
When they did mine it typically took about 5 mins but my car BARELY passed as it was "not stock"
Does the technician know on his screen when he's driving the car on the dynamometer if the car is failing or does he only know like me at the very end when the sheet prints out?
no the techs do not know if the car is failing, only the computer does.
