Neat idea about inspection info. I understand many states have equipment now that deletes the need for the dyno. However, if computer of 96 and newer vehs has been reset or battery disconnected it needs to be done about a week before test or it WILL fail! At least for emissions. People in similar states should know that. It doesn't mean the veh is bad - rather not enough data stored.

Be well,

Here in Ontario a vehicle with a MIL light on doesn’t mean an automatic fail for an emissions inspection, but the driver/owner is told that there maybe an intermittent malfunction in the emission control devices and then the vehicle is tested. If the gases are clean during the dyno test it passes.
The driver is also told that if the mobile smog patrol pulls them over for a roadside inspection they are libel to a fine under the environmental protection act, because they are driving a vehicle with a known potential emissions problem. I think the fines start a t $500. but don’t quote me on that.
During all my classes that I attended to prepare for my emissions repair tech license examination, I was always told that the only way to test the vehicle for NOX was under load and that meant a dyno test. What’s their answer to this down south, for not doing a dyno test?

Here In New Jersey, they do a load dyno test. Where an inspection employee runs the car at 2500 rpm's while the tires spin on dual rollers. I think this is really the only fair way to get a true NOX reading.

From what I here Florida needs your mobile smog patrol since they lack an inspection system. If New Jersey didn't have the inspections our roads would be more of a nightmare, with dead cars and traffic jams.

Here in Massachusetts, they still do dyno which once cost me a few hundred bucks when a novice tried to drive an 88 Town Car and had it up to about 120 mph and without load blew every seal in the rear differential! Ticked off! The car was fine the inspection lacked. I vote to eliminate all except safety stuff, period. Air pollution is no longer from cars. A few old cars won't change the world. Did anyone ever think of the pollution caused by just one space shuttle launch, or a volcano erupting?

Just my personal opinion for what happens here,

I forget to answer that one. I was told and witnessed just a plug in test for emissions was accurate for the vehicles that have that system. Massachusetts has probably the second (Only to Calif.) stricktest standards out there. I know there are states that don't test at all as they were considered not problem states.

They have changed the rules here so many times it's hard to keep up with them.

Here in North Carolina we only test obd II cars for emissions. We used to do a "sniff" test where we used a probe in the exhaust pipe and ran the car for 30 sec at 2500rpm and then tested during idle. We eliminated that test as of jan 1. Now anything 96 or older gets a safety only, which many people are pleased with. On the obd test we check for a mil light which will fail when turned on, and we check for readiness status. All but two readiness tests need to be set for 96-99cars and all but one for 2000-present cars. If the readiness test is not complete they get a "rejection" instead of a failure. It is a pretty neat system and reduces the amount of work for the technician. All we do is do a safety inspection and plug upthe computer to the car and answer a few prompts and pass, fail, or reject.

Wish Massachusetts would go that way. Just BTW a great friend and customer was here a while back for a sticker (I don't do them - just check out the car) and was rejected for bad tie rod end!! I was shocked as I cared for that car and the part really was bad! We were back with a new one in NO TIME flat. Same part was bad again a year later????? This is a customer who does the 3,000 3month thing like a religion and I use synthetic grease and did them all! I bought the car from him as I knew the care it had over the years as I did it. I don't skip hard grease fittings on anyone's car never mind a friend.

I'm glad it was found as I didn't even check for that. I have never had to replace a greasable front end part on any car I've owned or cared for on time for customers. Go figure? T

Word has it the Massachusetts is eliminating the dyno altogether. Too many problems and too many cars/vehicles can't be checked that way because of "AWD" and traction controls that just screw things up for a two wheel dyno. I can't imagine the unreported problems over the years now with the damn things up to and including one car going right off and thru a wall!
