Failed State Inspection (monitors "Not ready")
 

I took my car in today to get a state inspection. Unfortunately it didn't pass. This is my first Chevrolet & totally new to me about drive cycle. They say 3 monitors failed. Fuel Sys, Evap Sys, O2 Sensor. In order to pass, they say I need to do a drive cycle. Where can I go to accelerate 55 mph for 3 min & coast to 20 mph without getting run over,yell or honk at? Maybe real early in the morning on the highway ? Ugggggh, what a PITA.
The Vette is not a DD. I've only put about 1500 miles since bought it late Dec. 2017. Anyone else have this issue.

Usually just driving the car for a couple days in a row will complete the cycle.

Others have posted similar threads if you wish to search and get a larger perspective, but as I recall more driving time is typically needed... like already stated. All the BEST! :yesnod:

no battery change, the car sat for 4 days until I drove it in today for inspection

yes I will try to drive it more often. As mentioned the Vette is not a DD. I have 2 other cars that I rotates.

thanks guys for the advice

I rotate cars too - between my C7 and a 30-year-old Ferrari - I split the DD duties..... they're cars.

Last month I took my car in for an oil change and inspection and some idiot unplugged the battery and so they couldn't do the inspection. If you had a new battery or someone unplugged it then that's what the issue is. Just drive it about 100 miles and it should cycle the system back.

I live in Texas as well and failed the test for the same reason twice. I learned that using the Range devise to keep the A8 from going into V4 mode clears the codes and will cause the car to get a "Not Ready" when being inspected. The Range must be removed and the car driven for a couple of days to be ready to pass state inspection.

Yes drive it for a few days b4 testing.

You will NEVER get all the monitors up and ready in a hurry. But most states allow "all but one" or "all but two". I'd get a scaner, drive around until that number are ready, then head in and get it tested... that's what I had to do, and I still had a catalyst state not ready I think. Never did get them all ready, but they were ready a MONTH later when I checked!

I was also very literal and followed what I thought was the EPA drive cycle a couple of times, but it never did it.

So the question becomes how many monitors does TEXAS allow to be not ready? Tried to find what I could for you and came up with this:

I take my car into the Chevy dealer for annual inspection. .. figure they know what needs to be done to give my car back with insp.
never a problem.

Since I shipped my new GS earlier this year into Texas, it failed on the required inspection for initial registration. Mine at the time had something like 150 miles on it and the local dealer that was doing the inspection just told me to drive it a few more days. After another 100 miles, it passed.

Clearing diagnostic trouble codes with a scan tool, or some other gadget will also clear the monitor; making it necessary to drive the car until the monitors show passed.

Same happened to me in Tennessee with a new 2018 GS with about 10 miles on the clock, then I was informed that new cars don't have to pass emissions check until following year. So I just had it a year last October and it passed with no issues at around 1500K on the clock.
Make sure your state even requires emission check on a new vehicle.

Have the same issue. Purchased car in Maryland late December. Took it for state Pennsylvania inspection today with 220 miles in the clock. Local Chevy dealer said it failed emission test. Said I need to put another 100 miles or so on it. So that is what I going to do.

I took the car to the dealer this time & it passed with 2 "Not Ready". This was after 300 miles of driving.

OP, good to hear you passed.

Here in Ohio, bi-annual emissions testing is required if you live in any of the seven counties in and surrounding Cleveland. I guess the other 81 counties all have clean-running cars. New cars are exempt for 4 years, and cars 25 years old are also exempt. Ohio will allow one monitor to be not ready and still pass. We also have state self-test stations which are convenient and not require you to surrender the car to a testing technician. Testing is now mostly free at state inspection stations. IMO, this testing has questionable value as the cars that are subject to inspection have better emission technology as time goes by, and the older cars which possibly pollute more are not required to be tested at all. Expensive, silly system that arose out of the clean air act amendments of 1990.

Guy that used to live next door drove a beater Honda Civic that would have trouble passing. Always ran well and gas mileage was excellent, but it wouldn't pass emissions. He bought a cheap (about $20) OBD scan tool that would tell whether any monitors were not ready. He found out that if he drove the car hard with a lot of WOT, it would go ready temporarily. So for the six years he had the car, he would drive it like he stole it to the self-test station to get it to pass, and then not worry about it for the next two years.
