Default OBD Test to Replace Tail Pipe Emissions test in Ontario, Jan. 2013

I read this story in the wheels section of Torstar yesterday.
Act fast on drive clean loophole - you won't have it next year
It sounds like its possible that this new testing procedure may affect some of the modified vehicles out there, especially those with an EGR delete. What do you think?

I think most chipped ECU's will spoof the readiness issue and defeat the EGR CEL. I think it's a safe assumption that most tuners have experience with what will pass the OBD test.

Fortunately I can swap my non-OBDII ECU in if needed, but I think that they are only starting in 1998 anyway.


Easy enough to check if you are going to pass - do you have a CEL on? Yes - Get it taken care of. No - Good to go.

Unfortunately, this depends a bit on how smart the tester (or test procedure) is. Some tests first test readiness bits, then if they are good, they will clear faults (even if there are none), and then test readiness again. If the readiness bits still pass, they know that the tuner is spoofing the readiness bits, and you could fail. Therefore, it really depends on how smart the test (or tester) is. In other words, are they checking for a tune that tries to fool the test. A stock tune will not pass readiness after clearing faults until after a good drive. Only time will tell.

Have Fun!

Gotta keep in mind this is the Ontario government we're talking about here.

This is true. The question is: Have they done this? I do not know the answer to this question. You will have to ask your tuner.

Have Fun!

I'm not sure which states, but there are jurisdictions using an OBDII test at emissions time (thinking new york or California) Methinks this is ground already covered. Remains to be seen if all of the existing tunes in Ontario have this taken into account though.

I suspect that email volumes to Mark Malone and Jeff at Rocketchip will go up over the coming weeks.

I talked to the kid while getting my Jetta done last week.. He says they are pretty much going to look for a CEL and that's it.. I don't think anyone should be overly worried about it.

From the article...

"Under the OBD protocol adopted by Environment Canada, the on-board computer continuously performs a series of self-tests (while driving) of the various emission control systems. If a problem is detected, the OBD computer turns on the “Check Engine” or “Service Engine Soon” warning light.

Your vehicle will fail Drive Clean if the Check Engine light is on.

Further, the new test checks the status of the self-tests, also known as monitors. If the monitor self-tests haven’t been successfully completed, a Drive Clean fail will ensue. Erasing the on-board computer memory with a scan tool or by disconnecting the battery will clear all the monitors and again yield an automatic Drive Clean failure."

And

"Vehicles with monitors that are “not ready” will fail the new test. However, 1998-2000 model-year vehicles are permitted two monitors to be “not ready,” and 2001 and newer models are allowed one monitor “not ready,” and still pass. Most cars have four to five monitors."

Sounds a little more sophisticated than a CEL test, I'm concerned as to how the EGR delete is handled in the tune, does it count as my "one allowed" monitor not ready failure? If so, I am ok for now but what if they eliminate the "one allowed" not ready?

It would be good to know in advance if there may be problems. In my case I will be contacting TDTuning to see if there are any concerns with the way his tunes might affect my Jetta's Results.

I guess we'll find out when someone goes and tries to get test with no emissions equipment on the car, lol! Luckily for me I'm good for another 2 years.

I still can't find anything that states the visual smoke test for LDV's currently will be changed to this...

I'm not too worried, if your allowed 1-2 not ready monitors

Good thing the diesel beast got tested this past year

Maybe it will be a kit car when its due for its next test

Well one thing is without doubt. Light duty diesels will now get as rigorously tested as gassers.

Tests centres must be just thrilled with the new emissions tests, because it makes there $100,000 plus dynomometers completely obsolete.

I'm having a brain cramp here. Can someone explain the monitors to me?

Readiness codes are set by engine "monitors". Software routines that the ECU runs to verify the emission components are functioning properly. i.e. evap, cat, 02, egr, etc.

OBDII goes through several self checks to make sure that the systems are working (rather than waiting for a failure to set a code).

In gassers, the fuel tank needs to be able to capture any gasoline fumes and prevent them from getting to the atmosphere.

The ECU checks this by allowing a certain amount of vacuum or pressure into the fuel tank system, and then it monitors that pressure for a period of time. If the pressure drops, then the tank is not sealed properly (usually a bad gas cap), and it puts on a check engine light.

If you reset all the codes in the ECU, that status monitor for the Fuel system self-check resets to "not ready" because the test result has been reset, and the test has not yet run again (needs to be driven). Until the car is driven long enough, and the test is run again, the monitor will stay "not ready".

This prevents people with recurring issues from resetting all codes, and then driving to the test center, as the monitors for those tests will all read that not ready because the self checks have not run again.
