re: Check Engine Light Question - Inspection timing

In the five parish area around EBRP they have emissions testing. Usually they have to hookup the computer to the vehicle unless it is an older vehicle. They also have a gas cap tester. Computer decides if you pass or fail. If you pass the inspector types the emission testing number from the emissions sticker and sticker number in the computer program.

Outside the area it just a visual inspection.

Usually if you unhook the battery or do vehicle work they suggest driving it about 50 to 75 miles.

I have a friend who has a shop and saw how he does them.

The way computer works
First go to inspection page.
Ask for vehicle info and the inspector puts the VIN in.
Then go to page or maybe the same page says it’s a pickup, car, type of engine, year of vehicle, etc.
Then have page where check did you check vehicle, brakes, lights, windows, etc.
Then next page might be gas cap testing.
Then next if it has to have an emissions test ask you to hookup the computer to the vehicle.
If vehicle not required for emissions test it would bypass this or if the vehicle registered outside the 5 parish area.
Then say pass or fail.
If it passes then put the sticker number and if it had an emissions test the emissions sticker number.

Inspector fills out the back of the inspection sticker and puts it on the vehicle.

Go now. If you reset it takes time to cycle back and they can tell. If it goes off by itself and there is enough time after that reset, you should be fine.

If you have driven 150 miles you should be good.

I erased a check engine light code once and drove to an inspection station. Dude hooked up the reader, it failed. Dude asked if I had recently had any service done where my battery may have been disconnected and I said yes (I had also had my fuel pump replaced not too long prior to this). He said that he was getting an error code and could not give me a sticker, he did have to log it as a fail in his book and gave me an orange sticker but did not put it on my windshield as my current sticker was not yet expired (I had not waited for the last day of the month). Dude told me to drive it 150-200 miles and come back.

I did go ahead and replace the O2 sensor that had gone out and went back after 150 miles or so.

I had it happen a long time ago in my old F150. Battery was disconnected from doing something and I failed because it hadn't been long enough since the reset that it caused on the computer.

Where I go, I could easily plug my scanner in and reset it before any one knew. Is that possible?

Maybe the older cars don’t register a fail. My kids 2012 Toyota failed after having a new battery put in and driving it for about 40 miles.

I wonder how they are going to do the gas cap test since my new car doesn’t have one. Many new cars are being made without them.

Smoke test is pretty much the only option for capless systems.

ETA: It doesn't really matter for emissions testing, only if you have a leak code, and need to find the leak. If the SRT's are complete it proves the EVAP system has completed (X) number of confirmation cycles, and is holding pressure/vacuum.

Word is Texas is ditching the vehicle inspection requirement in 12 months. Apparently too much trouble getting illegals to comply. Mandatory liability insurance will likely be handled the same way

Most of the drive cycle is completed the first few miles it's driven.

The cat cycle requires around a 10 min drive at 55mph or higher.

This scanner let's you know when drive cycle is complete and ready for inspection.
