MAN YOU DID A VERY GOOD JOB EXPLAINING THIS!!! THANKS FOR MAKING IT EASIER

[@CarswithNash]

Thanks! I appreciate hearing that feedback.

[@alexandermonson4742]

Yeah got that same sensor for my 2012 kia sedona thanks to your video I checked for oil up in the engine area and loe and behold it saved me about 2 grand in repair work switched it out myself and although it's kinda hard to get back in there it's worth it.

[@CarswithNash]

It’s definitely not a fun job but I’m glad to hear you caught it early.

[@mohdalisyed]

Thank you so much for this video. I have recently bought a kia grand carnival (sedona in Australia)which has the same problem. Your video has given me confidence to try replace the sensor my self. I have watched your video 3 times already and will watch it a few more times before i give it a go.

[@CarswithNash]

That’s great to hear, thanks. You also might want to give the Kia dealer a call because I did have another commenter saying that some of these are covered under warranty now, like they extended it just for that component. I have no idea if that is the case or what the year range for it would be, but it might be worth checking.

[@xvassilli28]

Excellent video, I am gonna attempt this job myself, in a few other videos I saw you can get away without disconnecting fuel line, you can simply move lower intake to the side with fuel attached as it is very flexible.

[@odstrilla996]

Thank you for being so thorough, you really are knowledgeable🙏

[@CarswithNash]

Thanks, I appreciate the feedback.

[@commonsensepatriot9450]

It'll definitely go from a drip to pumping oil out in a short period of time. Our daughter's began with the oul light coming on, and the car was still full of oil. A week later oil was pouring out.

[@juicebox59]

Thanks for the video! I was able to replace the sensor on my KIA minivan.

[@CarswithNash]

So glad to hear, thanks for your feedback.

[@wallycleaver1046]

Great job on the video! I like the shortcut of not removing the injectors out of the intake, just the fuel line.

[@CarswithNash]

Thanks, I appreciate the feedback.

[@dans9462]

Thank you, very good video, very detailed.

[@CarswithNash]

Thanks, I appreciate the feedback.

[@youdagoob]

Fuel Rail disconnect. 9:56. Thanks. What I needed.

[@CarswithNash]

Happy to hear.

[@rodrigodossantos6029]

Thank you so much for the video! I have a 2012 Kia Sorento and After I changed the sensor and turned the car on it smells burnt, have you experienced this?

[@JDB321.]

You can come at it from the right side with a extension and universal with a 24mm deep socket

[@auricauric8150]

Excellent teacher. Thank you.

[@lincolnmaniac]

Hyundai tech i watch made a special wrench.

[@CarswithNash]

I guess if I was having to do this regularly I might consider that but this actually worked pretty good. It’s going up for sale pretty soon I’m just trying to get all the issues fixed first.

[@Leto4900]

Thank you so much for this great explained video. If my 3.5 v6 lambda engine rattle in a cold start that's means my oil pressure sensor fault right? Some people said also could be the chain n tentioner problem. I'm thankful if you can answer me.

[@CarswithNash]

I’m afraid the engine rattle has nothing to do with the oil pressure sensor or oil pressure. Both the cam phasers and tensioner can cause that issue, it’s very very expensive to correct. I had the same rattle in my engine and sold the vehicle as is because it was too expensive and time consuming to repair. Good luck!

[@Leto4900]

@@CarswithNash I'm gonna take it to the dealer and I hope it won't cost that much. Thank you very much for your reply

[@xvassilli28]

Many 3.5s do this death rattle on startup, usually lasts a few seconds, some are more loud than others. It's your timing chain tensioner, eventually it will fail and destroy the engine. I know people whose cars lasted for years with that noise, I also know some instances when it failed within months. Unfortunately the repair is extremely expensive and in most cases will cost more than these cars are worth now. There is a video of one mechanic on KZbin somewhere where he fixed the tensioner, but said he would never do this job again with engine in the car. It requires pulling the engine out. My advice is to drive it until it fails, you might get a few years out of it, then junk it or you can sell it to wholesale buyer like Carvana who don't care about these things but will give you below market value price.

[@Leto4900]

@@xvassilli28 now I'm in the 3rd year drove about 144k and still hearing that noise every dam morning. I'll wait until it breaks down I won't fix it that's my decision. Thank you again for your best reply 🙏

[@PhilMimo]

I have this same problem. Santa Fe 2011 V6 3.8 liters. How long does this job take?..My mechanic told me it's a big job...very expensive. What should I do ? Is it worth doing saving a 2011 car? Thanks

[@CarswithNash]

I did not think the 3.8 was an engine option for that vehicle… Are you sure you don’t have the 3.5? Either way it’s not that big of a deal, it took me about 4 hours total. If that is the only problem with the vehicle you should definitely get it fixed, but maybe get a second opinion because it sounds like your mechanic is trying to make it out to be more than it is.

[@artbyddp]

Oil light comes on after driving it was suspected oil pressure sensor and I found oil coming out of the connecter once replaced. What would cause a blinking check engine light if it was all put back together in reverse? Would it be the plenum and lower intake gaskets? I was sure to be careful with the gaskets and the lower intake gasket seals appeared to be flattened so would that cause a sealing issue? 2012 Kia Sedona 3.5l with 134k

[@CarswithNash]

Sorry for the delayed response you probably already figured this out. The first step would be to scan it and find out what the code is. If you have something like a lean fuel code then yes you will have a leak on one of those gaskets. You really should replace all those gaskets, sorry if I set a bad example by not doing it in this video but I was bloody frustrated with this vehicle at that point in time, it was one break down after another with that stupid vehicle so I just wasn’t spending an extra penny on it. I sold it right after this repair but if you’re serious about your car you should definitely put new gaskets in there.

[@ronniebrauda492]

WhaT do you think about moving the sensor to the firewall. Using a hyd. Line with a rubber protector

[@CarswithNash]

I have heard of people doing exactly that, just make sure you’re using high quality parts so there’s no risk of a leak and it’s definitely a solution. Athough it will take slightly longer for the oil light to activate in a low oil pressure situation, but we’re probably talking half a second at best. Personally I would normally just combine this repair with preventative maintenance like changing the spark plugs, coil packs etc, only reason I didn’t in this case was because I was already planning to sell it.

[@wethepeople409]

Kia extended the warranty for this problem look it up

[@CarswithNash]

That’s nice to hear because it’s a real pain in the butt job.

[@YoullShootYourEyeOutFrank]

Did they, for Hyundai as well? Do you have a link?

[@jjhard23]

After the intake is out, do you think that it will be easy from there to replace the oil filter housing?

[@CarswithNash]

Yeah if I recall it’s pretty accessible, I remember I checked all around it for leaks when I had it apart and it looked easy to get at everything.

[@jjhard23]

@matt77758 does it have any hose attached to it? My housing according to Kia is leaking and it's not the Oil pressure sensor switch. I'm considering to replace it myself.

[@panic151]

I have a 2017 Santa Fe, would this be the same process for mine?

[@CarswithNash]

If it’s a V6 model I would guess it would be rather similar but probably not exactly the same.

[@abushadi8639]

Hi how are you? I have Question Please, how many hour take This sensor to change it ? Thank you so much.

[@CarswithNash]

I think it took me around 4 hours and that included a lot of cleanup time because of all that oil that spilled everywhere in there when the sensor leaked.

[@vickiecharles2003]

Is there an oil pressure valve under lower manifold on 2004 3.5 Hyundai Santa fe

[@CarswithNash]

I’m sorry I can’t say for certain.

[@vickiecharles2003]

Nobody seems to know...if I could only find nobody. TY

[@user-vp9cn1iv8l]

Hi! How I can take out the water pipe! Cause a need change all Housing Oil Filter Change.. sorry

[@CarswithNash]

Sorry I'm not sure, I have never removed one myself.

[@music-vl4zm]

Do you have a part# for the aftermarket sensor?

[@CarswithNash]

Sorry I don't. I typically encourage people to look up the parts for their exact vehicle just in case there's a difference if there's a different year or whatever, that's why I don't include the part number in the video.

[@auricauric8150]

Where did you get the torque settings?

[@CarswithNash]

I find them online in various places, I normally try to confirm them from multiple sources.

[@panic151]

What did you use to tightened the sensor?

[@CarswithNash]

Irwin channel lock pliers as shown.

[@alexandermonson4742]

I got a 15/16th wrench to slide in there but you'll be moving it like 2mm at a time for about 30 minutes

[@jessesannext3011]

Is a torque wrench required?

[@CarswithNash]

Depends on your experience level, I’m sure plenty of people do it with just a ratchet who have experience and have a good feel for how much torque they’re putting on things. Since I had a torque wrench it just made sense to use it.

[@jessesannext3011]

Thank you appreciate the response!…..update turns out my 2016 kia sedona has everything exactly similar up to the point of getting to the sensor. There are some sort of pressurized lines in the way not sure if there coolant or ac lines. So I was unable to replace the sensor, however turns out it’s an extended warranty party dealership will replace no charge. But upon reassembly I didn’t replace the gaskets or clean with brake clean and now it’s making funny sounds, so hopefully when I do replace this will resolve the issue. I’d ask the dealership to replace them but they want additional 700 even though there removing everything to get to the sensor anyway. Makes no sense…..

[@npc-david5221]

What is the estimate time it would take to do this repair

[@CarswithNash]

Around 4 hours.

[@npc-david5221]

I replaced the sentencer now when I come to a dead stop my oil light comes on but when I start moving it goes off

[@CarswithNash]

@@npc-david5221 The old sensor was not doing that? If you just replace the old centre because it was leaking and the new one is doing this I would say you got a bad part (that sucks!). But if you replaced it because the old one was doing the same thing that could be an indication that your engine does in fact have bad oil pressure. (Oil pressure increases with engine rpm, so that’s why it will go off when you rev it)

[@AnbuVega]

What are the gaskets called at 18:35?

[@CarswithNash]

Intake manifold gasket.

[@ua7pyro591]

Should have used an oem part. This will need to be done again shortly.

[@CarswithNash]

The OEM ones are notorious for going bad as you can see by this one. In any case it never leaked a drop for the rest of the time I owned it.

[@xvassilli28]

@@CarswithNash I agree with you to not use OEM. The part you used in your video (Beck Arnley 201-1771 Engine Oil Pressure Switch) has many positive reviews on Amazon and other sites, Hyundai part is junk, it failed on every engine it's installed in.

[@YoullShootYourEyeOutFrank]

Hi all, I have a fix to prevent this happening or happening again bc this happened to me twice. Had to fix the rear main seal and pcv valve twice. FIX: Pressure relief valve set to ~4PSI

[@CarswithNash]

4 PSI seems a little ridiculous if that's in the oil pressure circuit? Or is this something you're putting into the PCV system? I definitely feel for you having to do that job twice, it's not a fun one.

[@YoullShootYourEyeOutFrank]

@matt77758 I've since made an update to have it vent at little to no pressure essentially making it a check valve as you don't want the case to pull air in under vacuum/ idle condition. Essentially it's a blow off valve for the crank case to accommodate if the PCV fails(again) it can also handle higher volume rate. I got pics if you want em

[@CarswithNash]

@YoullShootYourEyeOutFrank interesting. I solved the problem for myself by selling this vehicle shortly after I did the repair.😉

[@YoullShootYourEyeOutFrank]

@matt77758 This is the way 😆 my fix is a hail Mary, so much as squeaky belt and it's getting traded in 😂

[@hondacivics4life]

Lies not there I have a06 santa fe. 3.5. And nothing there pisses me off pulled intake for no reason

[@CarswithNash]

That would be annoying but being that this video was directed at ‘07-‘12 models you should have double confirmed yours was the same before starting.

[@dealerauctionnightmare4689]

What a BS design!

[@CarswithNash]

Agreed!

[@edwinjewell5359]

Pain in the a## engine

[@SAVETHEPLANET-KILL-A-GLOBALIST]

Intake gets torque to 38-44 ft lbs?

[@CarswithNash]

If that's what I said in the video then that is what I did and it it worked for me.
