Prius suddenly sputtered and died while driving, sulphur smell in cabin

If you have a misfire, that would cause all your codes and the symptoms. You don't have a P0420 (yet) because either you haven't driven the car so that it runs that test, or one of the present codes "blocks" the cat test from running.

It doesn't matter. Fix the misfire- usually is ignition (get name brand parts from reliable sources as counterfeits are known problem). Could be fuel quality and or injector. Could also be compression.

Running the engine long enough with a misfire WILL kill the converter.

If you have a failed cat, dont toss it or flat out replace it, until you try CLEANING it, PROPERLY.

For MELTING burnt on carbon, that usually needs to be wire brushed, there is only one product that works, chemically, i would fill that cat with it and let it sit overnight, then flush it with a garden house, then fill a bucket with warm water and dawn and dump it in there then garden hose flush it again. Try it, you will be surprised at the results on a failed convertor.

Berryman Chem-Dip Carburetor Parts Cleaner

Now wait DO NOT JUST GO BUY IT BECAUSE IT IS THE MOST CONFUSING PRODUCT ON THE MARKET
THEY HAVE TWO LOOK ALIKE PRODUCT AND ONE WORKS AND ONE DOESN'T AND IT WILL MELT AND DESTROY PLASTICS.

I am going to get the PROPER part number I have to drive to get it so stand by.

I use this stuff toe MELT carbon on valves egr traces piston rings, it washes right off and the carbon goes down the kitchen sink.

I use it in a harbor freight ultrasonic cleaner, it gets hot, i use it indoors,no problem with fire etc.

THERE ARE TWO PRODUCTS WITH THE EXACT SAME NAME AND TWO DIFFERENT PART NUMBERS, STAND BY...

 

That’s not how to regenerate a catalyst

 

These are TWO DIFFERENT CHEMICALS
The rectangular one is WRONG DO NOT USE IT
It is the REFILL for a different round can

The round can is the RIGHT product ONLY IF it has part number 0996 on the back of the can
There MAY BE a cost effective refill rectangle can for part 0996 if so I would buy that instead of the round can
THE PRODUCT IS REUSABLE OVER AND OVER, THE ROUND CAN HAS BEEN USED FOR YEARS NOW.





PART NUMBER 0996, THIS IS THE RIGHT CAN, IT MELTS CARBON
NO OTHER PRODUCT I TESTED DOES WHAT THIS DOES.





I ORDERED THIS NOT KNOWING IT WAS A REPLENISHER FOR THE WRONG PART NUMBER, THIS CHEMICAL DOES NOT MELT CARBON, IT DOES MELT ALL PLASTICS

 

I didnt post regen i posted CLEAN as in get stuff off of it, I have done it, it works.

 

Not exactly the same name.

Berryman PROFESSIONAL Chem-Dip Carburetor and Parts Cleaner 0905 is 40%
Methylene Chloride

Paint stripper

 

Yeah thats nasty stuff so do not buy it, the other one is nothing like that chemical in the rectangular can, that 0905 is some hazmat stuff man.

I didnt know I was buying that, the marketing on the cans is way too similar, now I have two gallons of that crap

When I opened it I thought GREAT, EPA MADE THEM CHANGE IT,
I put it in my ultrasonic cleaner tank
The rubber mat in the bottom
WAS GONE A FEW MINUTES LATER, disappeared.

 

Berryman has a couple of kits.

Did you remove the MAF sensor and clean the elements that are tucked down inside?

 

Maybe it's an Australia thing. Or even 'supply chain'? Selecting North America on the Denso website shows 6 available recommended models of DENSO spark plugs, including the SK16R11(Denso 3324) and the IK16TT (Denso 4701), both available from Rock Auto for about 8 bucks each.

 

I have used rock auto quite a few times, no issues

 

I have a set of SK16R11s in my 2007 that I purchased from Rock Auto about 5 years ago. Right around 80k miles on them now and still running flawlessly. I have 3 more sets in the garage ready to go for the other cars. Every Gen 2 Prius I've bought has gotten a set from RA.
