2018 Prime Premium Fails NYS Inspection @ 66,000 miles

Have a look at the plugs? I suspect they’ll be fine.

 

I would suggest that you should first burn through a whole tank of gas.......or near to it.
The transient misfire might have been due to the gas in your tank "aging" badly.
A dose of Techron might be a good idea too.

Then see if the code is still active.

 

how far back do the inspection computers look?

 

There's no need to put your EV range at 0. unless you want to do it that way. If you push the EV/HV button the ice will fire eventually and keep running if you're at hwy speed like I-81 to Binghamton and back. That should get you down between 3/4 and 1/2 a tank.
I also doubt there is anything wrong with the car. but you never know.
Might want to get the inspection at the dealer as long as Autozone didn't clear the code,
If the dealer was who failed the car forget going back to that one.

 

If it is bad gas that has been sitting simply because it wasn't being used by the ICE, you could try to use a fuel stabilizer.

 

NYS inspection must be more thorough than ours to be able to pick up the historical code that did not even trigger the CEL. Our state inspection usually does not even bother with OBDII connection. As long as no light is lit up on the dash, it's good. I think if the CEL never came on when the misfire occurred, my feeling is that resetting the code with any OBDII code reader would erase the past history. And if misfire never happens again after the reset, with new gas and running the engine on HV for a good while, then you may be good to go for the re-inspection. That's what I would do before spending $$ on other things.

BTW, this topic should be placed in the PRIUS PRIME Maintenance subsection.

 

Or can't you just put it in CHARGE mode and it will run continuously, no matter the speed?

 

in mass, we hook up to obd. you don't have to warm up the engine anymore. i just don't know what history the computer is looking at.
but after 9 years of mostly ev driving, it has never failed an inspection.

 

Depends on what your goal is.
Trading a $20,000 PHEV for a $40,000 BEV because the PHEV failed a state inspection on a technicality might not be the best move juuuust yet.
I'd at least try to leg things out another year or two in order to see if there might be more government cheese that you can squeeze out of a BEV purchase.

The economy is kinda stumble-stepping right now, and car supplies are being throttled by supply chain issues.
That's good news for selling the Prime, but bad news if you're looking at a new BEV.

The notion that you need new plugs or even a coil-pack doesn't bear inspection for an engine with less than 25,000 miles on it.
I think that you're dealing with bad gas.....

Good Luck!

 

And new car itch.

 

@FuelMiser Yes, for about 45 minutes or until the traction pack reaches it's cutoff voltage at %80 SOC or somewhere around 355 volts.
The engine can also be stated (most of time) by pressing the Defroster button. or activating it on the big 11" screen (MFD) in the models that come with that.

 

congrats!

 

I don't know about NYC smog laws; but out here - it's very difficult to fail a car for a pending code. If a smog shop is afraid to pass it; they'll tell you to go away and keep your money. This would be a honest shop.
Years ago, on my old Honda prelude - with dual side draft carbs and miles of vacuum lines under the hood; didn't pass smog. I couldn't believe it didn't pass. I drove it a few blocks to makes sure everything seem to be working correctly and had it tested down the street at another shop. It easily passed; when I compared the two computer readouts it was obvious that someone pulled a vacuum line between the low rev. and high rev. test. Thinking back I remembered that the mechanic was under the hood during the high rev. test. The first shop that failed me, offered to fix the problem for an additional $100. I went back to the first shop and demanded a refund. At first, the owner refused and I asked him who holds the smog license for this shop? Another guy shows up and looks at my computer readouts - neither of them did the smog on my car. I pointed to the other guy in the shop and asked them; are you willing to loose your business and smog licenses over that guy? They promptly refunded my money.

 

Any follow up? My guess is heat exchanger leak?
