That feeling when "Inspect Customer's Shoes" doesn't appear on the factory flowchart... LOL I am LOVING Kia-Hyundai right now for having known-good waveforms. That is awesome!
I bought a brand new Hyundai Elantra this year. My last new car was a 1999 Ford E150 oh, I never had a reason to regret the purchase. I've become extremely comfortable with my Elantra and have noticed that the car is being worked on tend to be high mileage cars. Some of that could be because of the warranty none the less the car is so for all appear to be in good shape and repairable.
I agree! All manufactures should give the cam-crank correlation waveforms! Even known good of all sensors!! They have all that info! It would make our life some much easier! Great diagnosis my friend! Stay warm!!!
Xln't knowledge Ivan, thank you! Between SMA & now your videos, I've become much better at diagnosis. Even on the simple, no starts/basic tech work. Positive thinking goes a long way!
wow good pickup there with the timing belt being out..ivan and pico scope to the rescue :)..helped to have a bit of service history also. Kia coomoon is that a nice place for a pcm!! LOL..
I recently encountered a vehicle that had a failing battery ground cable. The terminal had come apart but was good enough to start the vehicle intermittently. The oddest thing was that the missing ground would light up the front right turn signal and side marker light as the ground became disconnected. My only assumption was that the vehicle's computer was trying to find engine ground through whichever circuit was easiest. That just so happened to be the power wire for the front turn signal lights that connected very close to a main body ground.
I would look for signs of spilled coffee, tea or hot chocolate as probable cause for connector dislodging from foot/leg jerk reaction just to satisfy my curiosity. Nice diag, the scope does it again...😎👍
Ivan, this is Brian. For what it's worth, on the Lexus I asked about...it was a bad CKP sensor. Absolutely nothing I was seeing would have lead me to that. Was throwing ignitor codes. Finally found one line in an entry in Identifix under "tech-tip" that said a faulty crank sensor can cause ignitor codes. Thought I'd let you know, just in you ever see anything. Great videos as always!
@@PineHollowAutoDiagnostics I'm sure a good scope (like a Pico), would have probably picked it up, but unfortunately all I had was a much less expensive OTC. Not very many settings. But, it's fixed, that's what matters! On to the next headache...lolol....
These are great cars and they can easily do 300k if the timing belt and (auto)transmission fluid are changed per the OM... We have had 5 of these cars and they were/are the most trouble free of ANY other cars we have owned... BTW the very first timing belt replacement I did had the same codes and I found the number of teeth between the intake and exhaust cams was off by one tooth... You need to make sure there is no slack between the cams even though they may look "right"... The CEL will go off and the engine will run much better... I have an 08 Spectra SX (4 door version of what you worked on) with a manual tranny and it has much more pep than the automatic version... Dave
That's great with the waveforms! The Pico verified the problem. If the timing belt was changed recently, hopefully it will be an easy correction. Really bad place to put the PCM connector. At the very least, Kia should have put a cover over the PCM harness and connector! Nice Diag!
'Easy correction" means doing the entire timing belt job all over again. Not so easy-- that's why it's important to do it right the first time. The sad part is, they probably started and checked to see if it was right--- and it "sounds" ok, because the variable valve timing is making a corrective adjustment, accounting for the incorrection. So they start the engine thinking it's running fine, and put everything back together. smh..
That PCM latch needs a lock on it because of its location to the clutch and foot rest. Anyone could easily kick that clasp open with their feet unintentionally. The timing belt got put on wrong, amazing.
😆😆 Nice one. Way too easy for you. But hey after the Staten Island express you can use a break. You're right on the service info. Would be awesome to have known good waveforms given to us. 👍👍
Ivan, did you have to align the marks on the cam sprocket with crankshaft sprocket to get the timing correct? That ECM lock is kind of sketchy. Not very secure.
one of my friends has crank no start. avalon 2007, the code is camshaft. when i removed the connection of of it tried to start the car started, however if i put the connection back it wont start,is that normal??
On that engine the chain & or tensioner between the cams could be the cause or could have vvt issues as well. I just did a Kia Rio with the same design. Mine was not as far off as yours. It is a goofy set up. I think that the CMP tone wheel bolts to the back of the intake cam. Happy diag'n!
Im a hyundai tech in new zealand and well the same as kia same power train , i had a 2012 ix35 with that issue and the exhaust cvvt hub was sticking after 90kms of driving but these are timing chain , 9 times out of ten its lack of oil changes or wrong oil grade the PCM are in the engine bay now which is such a better location
I have a 2005 Kia Sorento I bought it drove it home turned it went back to start it and it wouldn't start up I the Water restaurant the starter and a fuel pump I'm going to try changing the fuel filter Dallas L cherry North Vernon Indiana
I pop the hood latch on my escape at least once a week getting out of the vehicle with my size 13 shoes. I'm sure if I owned this Car! I would have discovered this same no start scenario.
I don’t think the engine would have run as good as it did at idle with the timing belt being off even one tooth. I’m a little curious about if they were paying attention to where they initially set chain on the VVT. Nice job Ivan as usual
A nice quick one. Makes up for the previous Mercedes ignition key that hadn't been programmed properly and caused a parasitic current draw, flattening the battery quickly. Swings and roundabouts. change the Trans fluid to fix ? Yup there's another wun ! Good luck :)
I’m a bit surprised when folks rev an engine just after starting as if they don’t feel it’s running yet and revving insures that it is, isn’t revving the worst thing for an engine when sitting and cold?
It was puttering and spitting and missing--- sometimes revving will "blow the cobb webs out" or help get air bubbles out of the fuel lines, ect. Or just giving a little gas to an engine that is about to die. It was a perfectly normal reaction to hearing the engine missing like he did. (which turned out to be a spark plug test set up)
@@W.Khairi The oil starvation only happens for a second or two at most. Revving the engine shortens that time even more, by speeding up the oil pump. There is that initial moment, but it's almost irrelevant. Now for example, changing your oil filter. It can take a little longer because the pump is having to fill up that entire filter before it can pressure up the engine- So it's good to pre-fill your filter when you install them, if it's possible; and don't rev needlessly at start up on a fresh filter/ oil change.
@@calholli Many thanks for the clarification, but there is another factor involved when revving a cold engine which is that piston-rings don't seal +seat properly against cylinder walls when cold and therefore the high risk of cylinder scoring, piston-rings damage and excessive blow-by.
On kia/Huyndai I think the pcm lock has a locking mechanism itself in that - if I remember correctly - u have to press it down from the front to get it to open. So I kinda dismiss that it was accidentally unlocked.
Shouldnt you also check oil level and pressure. Maybe cvvt thingy locked up, might need releasing. Just high rev it a few times might release the lock. Worth a try!✋
I think the code description said thats the code is set only if present timing is outside of max vvt advance or retard, so even if the vvt solenid was stuck it shouldnt cause a corelation code but rather timing overadvance or overretard codes...or such.. My 2 cents, But really cool point none the less.
I hear Staten Island pays a premium for good used ECM's. I think someone was trying to steal the ECM and as you arrived you scared them away ;) Seriously, I'ld ask your customer what the previous tech that checked her car out before you was trying to sell them, was it a "bad ECM"; and was that tech from the same shop that was responsible for the shoddy timing belt job?
Of course i go to alldatadiy.com and try to look up my cars and i cannot find the wires to test. I miss my paper OEM factory repair manuals. This digital stuff is hard to search. Or somone needs to teach me how to find these wires on alldatadiy.com.
I can't be that lucky. I am working on a Saturn Astra 1.8l It has a P0016. Found the timing was way off on the back of the cams and the phasers on the front. Somebody was in there before me. The customer had me replace everything all OEM parts. Used the proper tools and got everything back mechanically where they are supposed to be. Still have the code. Without a scope and good wave form. Kind of at a loss. Am I getting a good signal from the cam sensor and the crank sensor.

I am a bit of a Hyundai fan, love my 04 Tiburon, but that is a TERRIBLE location for an ECU with that style connector! I like that it's easy to access and all, but having that connector in that location is just asking for trouble.

Began to think you had been setup, clever stuff it's amazing how easy it is for me (a rank amateur) to forget the basics.
Great commonsense diagnosis good job Ivan
Excellent diagnosis as always, forward thinking of Kia to provide known good scope captures, and you're right all manufactures should do the this

Ivan, did you have to align the marks on the cam sprocket with crankshaft sprocket to get the timing correct? That ECM lock is kind of sketchy. Not very secure.
I think your theory on their foot pulling the release is correct. That’s a bad design.
Maybe someone thought it was the hood release ;)
Nice one . Love the factory wave forms.

That pcm lock will make for a great cost effective immobiliser (until breaks off)
I've seen on some cars you need to advance the cvvt when you put the belt on. Its possible that Kia has a procedure like that which was missed.
@Sam S true. Just mentioned it for reference.
You've definitely been affected by your SIE experiences. When things are easy and go right, you can hardly believe it! lol Thanks Ivan!

I had a Sentra no start years ago and traced it to a stolen PCM. They were under the driver's seat then.
am suprised there is no lock on that lever. i could totally see doing that with my work boots
Good diagnosis. The lab scope is a valuable tool. Wonder if the shop that had you do the diagnosis did the timing belt?
Super cool on the known good waveforms from alldata 👍🏻
That was provided by Hyundai.
