Alfisti, looking for some guidance on this one after only finding an older thread on this topic. My 22 QV with 12.5k miles that I picked up in February has now thrown this code twice in the last two weeks, putting it into limp mode each time. I took it to the dealer after the first one and was told it is a common issue related to condensation build up. They simply cleared the code and told me to clear the code if it comes up again as there is nothing wrong with the vehicle.

Has anyone else experienced this issue? Does it really make sense to just clear the code on a less than a year old car and assume it's fine? My dealer never has any loaners available so it's been tricky getting it serviced and still getting to work. Just trying to get a gauge.

P.s. not my thumb in the pic. I'm not that manly.

If it’s anything like the 18 qvs those sensors pop out of the hole they sit in. I think misattached at the factory? If you search around there are a few threads on it, I had the issue myself. Once you find it it’s a 2 second fix. Just hard to find as it’s a bit buried.

Had the same code a year ago when temperatures dropped, MY21 QV. Dealer had it in for about a month working through diagnostic steps and replacing various parts, including the sensor in question. They ultimately fixed it by replacing the PCM. Car had been perfect since…until last week when the code reared its head again. Just like last year, I have both P2C33 and P2C34. Heading in on Friday.

Last year the dealer commented that this is something they’ve seen not uncommonly in QVs. I know off at least one other poster who’s experienced the code this winter.

I had this too. It's hardware related and a new part is needed. Search the forum for the cel code under my posts (sorry there are 6k plus of them lol) and you'll find my detailed experience with it

@MDriver had this happen too

 

[Kuffs]

Sorry to hear you are having that issue again. Hopefully the dealer can straighten it out this time.

Appreciate the help and feedback - I'll look through some of those older posts to see if I can find that part number or see if it was simply mis-attached from the factory.

Hey guys, I had a 2020 Stelvio QV (I come in peace). I hang around your forum every once in a while to see how the other half lives. Anyway, I am VERY familiar with the P2C33/34 crank case pressure sensor malfunction. My custom-ordered QV (which I got with 11 miles on the ODO) popped the code at 4,500 miles driving to work one cold-ish morning, the car never went into limp mode, was in service for 126 days and they never solved it so the car was purchased back by Alfa as a lemon. I ended up getting a 2023 stelvio QV as a replacement.

They changed the sensor, PCM, wiring harness, you name it they did it, but that stupid code kept coming back randomly. What I eventually did was just kept clearing it even though it was a "stored code." Sometimes it would go away for 1 day, sometimes for 1 month. I will always wonder what the solution to this stupid code is. P2C33/34 still haunts my dreams!

 

[Kuffs]

Well, that is certainly not good news. I cleared the code last night and boom, it popped up again this afternoon while getting lunch. The car is now stuck in N mode until I try to clear the code again. I reached out to my dealer, and they are going to do a "Star Case" with Alfa where they apparently work directly with a technician in Italy. I hope they get to the bottom of this, but your story definitely makes me a little skeptical. I am glad to hear Alfa took care of the situation for you (even though 126 days in the shop is crazy)!

 

[Franiacob]

Yeah it was this huge saga, they would replace a part, give it back to me, a few days later (sometimes a week, sometimes just a few hours) the CEL would return with the same code. We went back and forth for months, opening multiple STAR cases, multiple emails back and forth from our service department to Italian engineers, they flew in some "alfa specialist" who spent the day with the car (this is when the PCM was changed), which solved the problem for maybe a week-ish. Towards the end of my time with the car I would just simply clear the code and wait for it to come back. Ironically I had the car for an entire month before the buyback was finalized and the code never came back during that time. I'm really curious to see if Alfa has a "good" fix for this given that the problem has been around for a while and cost them a buy-back. I would assume they'd be on it by now, jeez!

Came up for me as I pulled out of my work parking garage a few weeks ago. Went into N mode. Other than being stuck in N mode, I didn't notice anything odd about driving characteristics, noises, etc. It was 46 degrees in the garage according to the thermometer on the dash. She's just over a year old with 20k. No problems before (except a cylinder 6 misfire code that disappeared right away while on the track in May of 2022). Dealer cleared it and it hasn't returned....yet. They said, "punch it and see if you can make it come back." Love it. Just waiting for it to return. I'll be keeping a close eye on this thread.

 

[graymatters]

First time I went through this, the tech commented that the last step on the treatment "algorithm" for this is to drop the engine out and replace all of the wiring. "A huge job" per his description. Didn't get to that point the first time around, but let's see what happens this time. Hoping for a solid fix - would prefer not to be in a base loaner for a month again.

Found my thread
Anyone get this CEL before?

 

[Kuffs]

Still waiting to hear back from the dealer and will continue to update this thread once I know more on their potential fixes. It seems like Alfa has done a decent job of fixing issues over time so I find it strange that this seems to be a known issue that impacts all model years (and Stelvio QV's for that matter) with no known, clear fix.

@Avync11 thanks for finding that - I did try to search your threads but did not see that one haha. I will give it a look.

I had to contact my dealer as I had not heard anything back yet, and they will apparently need to keep the car for an unknown length of time. Of course, no loaner cars are available until the end of January so they had me reach out to Alfa Romeo Customer Cares for rental reimbursement. The kicker is that they will only reimburse me for $50/day; the only car Enterprise has at that amount is a Nissan Versa.

So somehow, after buying a brand new Giulia QV 10 months ago, I will now be daily driving a Versa for the foreseeable future and crossing my fingers they will actually reimburse me for it. Sorry for the rant, but this is just ridiculous and not at all a "luxury" or "premium" experience. Not hating on a Versa or economy cars at all, but it certainly makes it harder to continue rationalizing my car payments.

For me the car was stuck in N so while I waited the week for the dealer to receive the part, I still drove it. Can you not try and do the same? A qv in N is still better than a versa lol

 

[Kuffs]

Haha that's a good point and something I did consider, but the service department currently does not know what the solution is or even what part to order. They asked to have the car for some time to try to figure it out and were non-committal on how long it would take. I will look through your thread though and pass that info along to them to see if it helps.

If your car throws a code then they should have it in their service manuals on how to fix it, especially if it's the same code as mine

 

[Kuffs]

Right, and considering this is the second time I brought it to them for the same issue, it shouldn't have been a surprise. But they responded that it needs a new sensor and wiring kit so we will see.

 

[dantegl36]

I had this issue on my 2018 QV. The dealer was not smart enough to fix it the two times I took the car to them. I dug my hand in, found the sensor, and popped it back in. Code has not returned since and that was close to 8 months ago.

Haha wow. If this solution from the dealer doesn't work, I'll take your advice and just try to find it myself.

 

[MDriver]

they need to change the part...I believe @Alfissimo sells an updated part with metal replacing plastic.
BMW had the same issue with the water pump impellor on the E36, it was plastic and failed consistently until the plastic was replaced with a metal piece
