Shopping for an oil control valve 243603C810 for Genny 2009

[sm77]

Hey everyone. First post here!
My 2009 Genesis with 56k miles recently developed the engine shaking problem. Had it checked and got 4 codes: random misfiring, cylinders 1, 3 and 5 misfiring, and p0026 which is Intake Valve Control Solenoid Circuit Range/Performance Bank 1. The dealer ran some tests and decided that oil control valves need changing. They quoted $170 for each, with $150 labor. However I could find the OEM parts for around $130 online (for example here). Then I searched ebay and I found this which is under a $100. The catch is, even though the ebay one has exactly the same part number that I need, it says it is not good for my Genesis, only for Kia Borrego. I have a feeling that their system is not accurate and the part does fit the Genesis, because the engines seem to be the same and the part has a Hyundai logo on it as well (and the part numbers match).

My question is, will this fit my Genesis? Is it even possible for two parts having the same part number but belonging to two different vehicles and not matching each other?

Lots of Hyundai and KIA parts overlap and if it's genuine OEM and the correct part number you're ready to rock.
Here's how to identify OEM parts: http://en.mobis.co.kr/pure/contentsid/2033/index.do

Thank you. Happy to hear that! However, according to this Wiki page, the engines used in Kia Borrego and the 2009 Genesis are slightly different, in that the Genesis one does not have CVVT on the exhaust side. Since the part I am interested in relates to the exhaust, do you still think that there is no danger of mismatch?!

Btw, as far as I remember I saw the code P0026 which is about the intake solenoid circuit. I don't know why the dealer wants to replace oil control valves on the exhaust side. Does this make sense?

I never questioned the part number as it was supplied I only did a PN search.
Check this page and see if that's what you are looking for: http://www.wholesalehyundaiparts.co...--EX-LEFT--LEFT-HAND-/8508819/243603C810.html
I don't have first hand knowledge of this problem but here's what I found for P0026 with causes and solutions: https://www.obd-codes.com/p0026

 

[sm77]

Thank you. Yes that part is the one I am looking for (i.e. the part number is accurate and correct). The concern is whether the part I found on ebay by this part number will match my Genesis despite the fact that it says it is for a Kia Borrego... You can take a look at the ebay page for the part here.

I contacted the seller (fourgreen.com is their website), and they also said it will fit the Genesis. I think I will go ahead and purchase the part!

Update:
The parts did fit, but the engine issue was not resolved. The dealer called their Hyundai masters and they said oil might be disrupting the wiring harness. They tried to clean the oil but to no avail as of now. Here are a couple of questions for the more technically savvy readers!
- Is it even possible for oil to be disrupting connections? I mean, is oil that conductive?
- Is there a way to make absolutely sure the harness is malfunctioning? The engine harness costs more than $1500 so I don't want to go replace it just to see if it is the problem or not.
- If there was no option but to replace, is it possible to purchase parts of it and repair or does it have to be purchased all at once?

I would question whether the correct OCV was recommended. P0026 relates to Bank 1 intake side. Bank 1 with Hyundai's is the RH side. The part # they gave you is for the Bank 2 (LH) intake side. The picture in the parts catalog is a little misleading. It does look like the intake OCV is close to the exhaust, and the exhaust one is closer to the intake. Could be their parts guy looked at the picture and didn't pay attention to the actual description. It happens, I've done it myself before.

Also, if it is a harness problem, there is a small harness the connects the OCV to the engine harness, which is sold separately, and is really cheap. Might want to look into that.

 

[sm77]

Thank you for the response.
Regarding your first point, they actually replaced both the left and right exhaust OCVs (I mentioned only one of them here for simplicity). They also showed me one of them with clear evidence of oil leaked into it. So if they are being honest about that, I think the replacement has a good chance of being fine.

Regarding your second point, I'm with it entirely. I will go see them tomorrow and will bring this point up. If the harness is damaged because of oil leakage from OCVs, why change all of the engine harness? Doesn't make sense to me. Only the connection between OCV and the rest should be cleaned/replaced. They supposedly spent all of today cleaning this harness. At this point I don't know if they know what they're doing...

EDIT:
Forgot to ask, does that connector have a specific name or part number? How can I figure out what it is and search for it online?

Post or PM me your VIN # and I'll look it up. There are 3 part # possibilities. Most other models, this harness is part of the engine harness, and it isn't show with the harnesses in the Genesis catalog, so they probably missed it.

Update:
I went there and looked at the harness myself. It seems that, weirdly enough, oil has somehow crawled up the wire all the way through to the connection to ECM. They said they haven't seen such a thing before, but Hyundai guys say there have been cases. See the attached pictures. They were in fact trying to get this connector cleaned, but as you can see from the female side, the holes are too deep to be cleanable. We tried dismantling the connector without success.

As of now, they asked me to replace the engine harness, with part number 91242-3M810, but this is too expensive and includes all the harness. I asked them if it is possible to only replace the part that is bad and they said yes if it fits. I found this part on ebay. Could you take a look and see if this is the right part. I'm not sure if this is in fact a portion of the main engine harness or not, but this does seem to have the right connectors (and the repair guy said it should fit from the picture). The harness is supposed to connect the OCVs (and the corresponding sensors) to the ECM. Out of two connections to the ECM, only one has the oil problem...

Without your VIN #, I can't tell you if it's correct or not. There are several possible part numbers for the harness, depending on options and production dates.

 

[dougmcp]

I don't quite understand the reasoning behind replacing wiring harnesses because there is some oil on the contact points, have you tried a spray contact cleaner on the harness connections?
There are myriad cleaners out there by WD-40, CRC etc. available everywhere.

 

[sm77]

The reason, as they say, is that oil has gone through the harness from the oil control valves through to the ECU. So even if the connectors are cleaned, there is still oil in there which can potentially seep out again. The only repairy solution would be to dismantle the harness and clean everything up nicely...

 

[sm77]

Update:
Replacing the ECU wiring harness did nothing about the misfirings, but the codes changed a little. Now we have the random misfiring code (as before) and a new P0016 "Camshaft Position A - Camshaft Position Correlation (Bank 1)" code. The dealer contacted their Hyundai masters and they said to inspect the timing chain and the related components. Without any visual evidence of an issue, they have recommended to replace the CVVT with part number 24350-3CAC0 "since the engine has already been taken apart"! Looks like a blind shot to me but they say even a hairline of misalignment from the inside can cause misfiring. Anyone has any idea if this makes sense?

 

[GarnetTy1473]

Only problem with that is that the 24350-3CAC0 has been discontinued, and updated to a 24350-3C113, which will not work with the old cam shafts, so you will need to replace them with 24100-3CAM0 (LH) or 24900-3CAM0 (RH). Sounds kinda risky for the price, not knowing if it's going to fix it. List on the CVVT is $224.00/ea and $331.97 per camshaft.

 

[sm77]

The 24350-3CAC0 part is available at a couple of online stores, like here, for about 150 dollars. At this time I don't have much choice. The engine is all torn apart and if I say I don't want this replaced, and it turns out that this is the part that causes the issue, they would charge me a lot more than the part for labor! On the other hand, if they replace it and the problem is not fixed, I can't ask for the part back because they would charge for labor again, and it is hard to prove that the part was fine in the first place. Unless there is some kind of policy that I am not aware of, I have to go with what they say at least in this case.

That site is ran by another Hyundai dealership. There isn't a dealer in the country that shows the 3CAC0 in stock. Their online catalog is just pulling numbers and prices. Even Hyundai's catalog doesn't show the updated part #. So unless they have some stashed away somewhere that isn't in their inventory, they won't be able to get it.

I may have missed it but is the engine V6 or V8?
