Anyone out there have a diesel fail aircare or hear of this happening.
This truck driver who hauls loads out my work took his 94 Hilux through the Vancouver AC station and was handed a failure,his truck does not blow any smoke at all....I think he was scammed.
I have taken several diesels through yearly and never came close to failing, he said they got in it and reved it up and ran it through the gears,I told him they should only have put the probe in his tail pipe and idled it for a minute and that is all.
Has anyone had anything different from my experiences with aircare
.
 
They've driven mine the last couple times through. One of those monkeys can drive your rig bad enough to make it fail. Rev it too high, drop the revs too low, then hammer it to bring the revs up. Makes me ******* crazy.

The sooner they get rid of this scam the better. Of course they never will...
 
I/we have talked about this a lot. Joke is, Toyota diesels never fail AirCare. You are correct about the test, they never run them through the gears, just an idle test. Even my smoky diesels never had a problem, the turbo'd 2H had a ton of smoke billowing out of it and never failed AirCare. Sounds like they were treating it like a gasser. Get his copy from AC, I believe there are only two categories that have to pass with a diesel, three with a gasser.
 
I do believe that you can request to 'drive' your own vehicle for these tests.

They used to do the 'driving' test but the last few years only idle on my diesels.
 
I'm going to your aircare next time if all they're doing is a sniffer test. I can't STAND letting those boobs drive my trucks. Useless morons.

BTW, the only diesel I ever had fail was an 81 VW Rabbit. It was total driver error, the guy could barely drive a stick and knew s*** about driving a diesel. I went home, came back, ran through with a different driver and passed with flying colours.

Aircare is a joke and a scam. GRrrrrrrrrr....
 
they put my 81 on the chassis dyno and put it through the gears this time. 5 trys and the screen said to re try. The girl loooked frustrated and told me to drive to the end where I was handed the pass paper that said I had a 0.0 opacity. Such a bunch of BS.

This exact same thing happened to me, only it was three times. Every time, <0.01% which required a supervisor over ride.
 
No problems with mine, only an idle test. I think the max is 30 for opacity (I can't remember the units), and I blew like 0.9 or something ridiculously low.

In Abby, there are separate lanes for diesels and AWD vehicles because they don't run them on the dyno's I guess. (mine didn't that I remember for sure).
 
So if a diesel that does not smoke at all and has low mileage fails the test how would you get it to pass I cant think of anything possible that can be done to the injection system that could be done to pass aircare.
Would veggie oil help burn cleaner

My bet is driver error. I'd just run it through again. If it fails twice, there's probably a problem. Maybe. Or not.
 
for the longest time they just idled it through, last year they drove it, when I asked about it they said that they do it to put a load on the diesel. I did notice a slightly higher reading but I don't like it when they drive it as they have no clue about driving diesels. If if failed, and it's true there might be an issue, either the diaphram, injectors, air filter, etc. Personally, the next time I go through I will press the point of driving it myself or riding shot gun. If they don't let me I'll start using my buddy's address on Bowen to insure my truck.
 
Just ran my BJ74 through in the last month in Abby and it was load tested. The tester could not drive right, so it took a few tries. It almost jumped off the dyno at one point. Kept in in 4th when it said to go to 3rd as well. Lug city coming up a sim hill to the shift into 5th. Passed, but with the highest numbers I've ever had on it. I too would prefer to drive it myself.

I had one truck that was so smoky I was worried it would not pass. Like smoky enough to fill the bay. Passed.

Sump'm is up with that result if it's burning as clean as he says.
 
Each time I have had the tester take at least 2-4 shots at driving it. The major problem which they don't seem to be able to correct is that their computer runs the Safari as a V6 Pathfinder. The shift rpm is of course way off and pretty much mission impossible. Last year the woman "driving" it gave up after the third try and one of the guys drove it. He said I should tell the tester that the first two gears are low. I told him that they should change their computer track to a Safari and not a Pathfinder.
 
Diesels DON'T fail unless there is a MAJOR problem. I had an '84 BJ60 with so much blowby I had to check it before I got to the AirCare station. If it was a good day with little blowby it would pass with flying colors otherwise it wouldn't be let in the building!!
 
They just idled my 60, the AWD 81 gets the dyno test every time.
 
A customer went to aircare the other day. They did the load test and failed it. This is a pretty clean running turboed wagon but they bogged and beat on it and it received a fail
