Any emmision test tricks?

Perry Mason said:
What appalls me about this thread is just how many of you are willing to offer advice on how to break or go around the law... how to cheat!

In this case a law that exists for protection against an obvious danger for all of us... our ability to breathe!

Excuse me... but that is sick! :mad:

Actually at the time of your post there were 9 calls to fix the car vs only 4 cheat suggestions. That was certainly a better ratio than I would have ever expected.

Does any car ever fail?

I had a 6 year old van, that never ever had a tune up or change of spark plugs, pass with flying colours.

I always assumed the program is a scam intended to help the car repairers.

It's not a scam although some service facilities may be scamming.

I was involved with the program since the beginning. The program is monitored thoroughly and the fines and penalties for non conformance are steep. Some providers have been criminally charged.

If you consider testing equipment cost's $50K - $60K with a fail rate of less than 8%, the service facilities that got into the program don't see this as a money making endeavour.

The fact is, if you maintain your vehicle it not only improves the chances of passing an emissions test, but will save you money. Particularly if you consider the cost of fuel these days.

No testing whatsoever, you just pay the fee.

I don't see how that's possible, cars are hooked up to the Ministry of Transportation Computer when doing emmissions.

Not true. If you fail the test you can do repairs up to the $450 limit and if the car still fails you get a Conditional Pass. This allows you to renew your plates, but if you sell your vehicle the new owner cannot license the vehicle for the road until it pass the E-test.

Diesel emissions are tested differently than gasoline emissions.

A diesel test consists of anylizing the particulate matter in the smoke, not analyzing combustion gases. Heavy trucks are tested differently than light duty vehicles.

There is currently no loaded test for light duty diesel vehicles. A visual inspection is the only method used.

Could be something to do with it being diesel or possibly the are one of the scammer garages that submit data for another vehicle in the place of your vehicle.

As was mentioned previously most garages don't make money off of drive-clean inspections. (Since the fee we're charged doesn't cover the time of the mechanic to run the test.)

By giving danmand's car as 5-minute "test" the garage got to pocket the fee and still have their mechanic doing profitable work.

Diesel is tested differently (particulate matter in the smoke). There is no loaded diesel test for light duty vehicles, just a visual.

Thanks for the info. I didn't know that (never owned a diesel).
 
You can pick up the ""guaranteed pass" product at Canadian Tire for $29.99 or so. It recommends adding the bottle with a tank of gas that should be emptied before the test. I think it also suggests letting the car run for 20 minutes before taking vehicle in for the test.

As I said, diesel cars are not tested. You just pay the fee. I would maintain that is pretty close to scamming.

And for cars with advanced tracking systems (i.e. 500SL) there is no load test either.

The technicians are supposed to examine major components before starting the test.
I don't think this would work anyway as HC's are not the only emissions being tested. It would cause a misfire and more than likely fail the loaded test on the dyno.

In most places the technician is not a fully licensed nor highly experienced mechanic. They are usually apprentices or just gofers. They only do a perfunctory visual inspection and not allowed to touch anything.

Unplug the wire harness to the injector, block the electrical connection with a piece of electrical tape and loosely fit it back on. Most engines will run with one dead cylinder, you have to test which one will give you the least roughness.

The idle test produces the highest readings and most fails are based on these numbers.

The vehicle is supposed to be inspected but you're right, not tested. I still don't see it as a scam.

Likewise for vehicles with disengagable traction control and all wheel drive. Like any emission testing program there are exceptions.

Still not a scam though.

If you had a diesel car and took it in for emission test, and the mechanic looked at it for 5 seconds and charged you the same as for a real emission test, I think the word scam might pop into your head. Certainly, if a liberal politician tried this, you would cry bloody murder.:D

You're right about the technicians qualifications but wrong about them being able to touch anything. If a vital emission component is disconnected and can easily be reconnected (ex: EGR valve or vacuum hose), the technician is supposed to do so. I've been away from the program for a while but I doubt this has changed.

This could also trip a misfire code and cause the "check engine" lamp to come on. This would mean an automatic fail.

CO and NOX are also measured in the loaded test and a misfire could bump these numbers up.

The idle test produces the highest potential HC emissions but not NOX. NOX can only be measured under load.

Not much of a scam if the windfall is $30.

As I've already said, diesel has to be tested differently. Until the program incorporates a loaded opacity test (with the requirement of additional testing equipment) a visual test for diesel is the only method. It's not perfect but light duty diesel vehicles are a small percentage of the vehicles being tested.

If your diesel was a smoker, it would have failed. Not all light duty diesel vehicles pass the test....er.....inspection.

Wonder what the process is for Vin Diesel?
