GOT PROBLEMS OR ISSUES? => DIESEL => Topic started by: tw2005 on November 19, 2016, 03:43:22

Well the i30CW I just got literally crapped itself about an hour ago. Was running flawless then suddenly the gearbox dropped to neutral.
I had just stopped at a house to pick up a headlight assembly, reversing out I was trying to angle the nose so the front did not bottom but failed and copped a good knock.
Selected D,in gear drove off about 20-30 metres in 1st then suddenly engine RPM flared, no Drive. Select R get R but harsh, Stuck in third but can go manual 2nd, manual 3rd,no 1st no 4th.
have to manual shift 2-3 that's it.
I think I may have smelt something like electronics burn, could be in my mind.
I know the harnesses can suffer solder fractures. Hoping it's that but do these have a separate transmission computer?
I know the main ECU is in the engine bay.
Any help appreciated, about to embark on a very slow 70km trip back to base where I'll use my hatch for fault finding parts but just not sure if I'm on a goose chase for the TCU.
I guess the workshop manual should clarify this. :blubber:
Also, no error codes or lights on the dash yet
-
Bugger! I'll summon the troops.. @cruiserfied @nzenigma good luck hope it's not too expensive!
-
There's an acrid electronic odour in the engine bay mainly near the fire wall. Initially thought ECU,pulled it out no odour at all. Just before it went to shit the dash display was flickering.then stop. I started the car and then after about 10 sec total death.
No more gear indication, engine lights or coil lights.
Thinking ECU I pulled it out,was going to open it up but then plugged said dead ECU into dads and all lights were good, coil light etc was good and of course the immobiliser light was blinking due to mismatch.
so ecu is good I feel, just don't understand now what it may be unless the dash is part of the issue, weird
-
Still working the problem but found the primary issue and cause of the acrid smell. I don't know the exact names of these sensors without a reference but looks like a speed sensor at the back of the box has sheared and shorted to earth. The front sensor also was off and I have not touched these.
The front sensor (input speed sensor) Looks like there is some corrosion and hard to get seated so most likely incorrectly fitted.
The back sensor (output speed sensor) reeks electronic burn.
Since the dash was flickering I'm saying it was bouncing on the gearbox casing and has blown something.
I just can't find what cct looks after the Gear display, coil ccts etc.
Hoping someone with in knowledge get s back to me soon.
The sensors will be a piece of piss but this secondary damage is driving me nuts, if only I knew then what I know now I could have isolated the short and limped it home.
Bugger.

Final piece of the puzzle, Fuse No. 11 in the engine bay fuse box 10amp,open cct.
Looking at this sensor 4262039051 the plastic looks real brittle and heat affected.
So I'm going to replace both.

This one 169K, my hatch I got it at that and it's 191k nil issue with that one.
The wagon has had a rough life but it has been serivice by Hyundai recently as it has the srvice sticker an d has a genuine air filter.
Motor is good, trans is smoother and better than mine.
But it looks like it's been in the sun a bit or in high heat maybe NT. Previous owner was Army.

Now back to the transmission speed sensor. Photos can not reproduce the beautiful aroma of a burnt out electronic part, but heres some shots.
My previous vehicles have been Mitsubishi and I know a fair bit of Mits designs or engineering have been in Hyundai for ages.
The A4CF2 is no different and is based on F4A41/42 Mits except the valve body arrangement is definitely different.
I had the pleasure of a F4A51 Magna box go which was a wty job / "Rebuilt to Mitsubishi Specs" by fluid drive that lasted a whole 60 000k, a long story.
I kept some parts and sensors from that box( rainy day / hoarding syndrome)
Just got back home and all the way I'm thinking I've got those sensors I may be lucky.
Physically is the same , connector type same, just not sure about internally.
Will let everyone know, it may work ok, may not. Looking at part numbers and aftermarket numbers they're not matching but I'm giving a shot anyway. It's just a magnetic pickup surely it'll be close(LOL)
This is the failed sensor put back together, it did not shear off, more likely burnt away and popped out. Notice the tip of the sensor is raised like heated plastic, Looks like this was burning away internally and got hot.

Thinks!!!!!!!!!!!!!!!!! :confused:
A hard knock ( impact) you describe would not normally cause this problem . Its probable that past repairs have left some wiring that is vulnerable eg. insulation stripped , therefore it shorts out.
The turbine speed sensors (pictured) are wired in parallel .
They have three leads; the same 12v supply goes to pin 3 on the front and the one on the back of the trans. They have a common earth (pin1).
Pin 2 are separate signal lines to the PCM.
You say you have exchanged the PCM and find its ok.????
In normal use a sensor will draw little current; so to cook it, you have to short pin 2 to ground or to the 12v supply.
So I would be looking at the plug on the burnt sensor, the wires are close together, if it has been stressed they could touch each other.
The sensor may have been cracked before you thumped it. But you will need to put a meter on the wiring before you replace it because it will cook again.
As said..just thinking hope this helps. :)

Yeah, I think it's coincidental but could be some dodgey work previous. Already I had replace the LH headlight as the bulb clamp was broken and someone siliconed the globe in and had it perfectly aligned with the trees.
All I've done with the PCM was hook it up to another i30 to find the gear indication and engine/coil lights worked which i lost in the process (fuse 11)
The input sensor I found disconnected but that may have been because the wiring harness is also attached to the valve body harness and got pulled when I removed that.
It certainly was very hard to get seated and latched so I feel that one was not on all the way.
So are you alluding to potentially wiring issue cooking it?
It was running 100% fine and the failure was catastrophic with no prior signs of it going.
What has me curious is how the two parts separated unless it was already fractured and someone pushed it together with the pins still connecting.
Comparing the mitsubishi sensor housing to this one I am wondering if some water has ingressed in between the two parts and started a burn which then made it more conductive and shorting more burning it out.
That would make sense based on what you're saying what would need to happen for a burn out to occur.
The quality of the moulding does look less than that of the Mitsubishi equivalent and there is an air gap after mating the pieces together of the Hyundai unit.
-
something else, there is not a mark or scratch on this suggesting it's been impacted. The whole scenario is unusual .
-
something I would like a hand with is two things are now present which were not before after fuse replacement.
Check engine light (orange engine) and the ESP off is permanently on.
I'm hoping the check engine light is the missing trans sensor but the ESP off, is thatsomething that needs a dealer to clear?
I'm thinking with all the fuse and relay pulling I may have triggered the ESP and if it's anything like the Airbag systems in cars, I'll need a dealer, just hoping not.
-
Was it the sensor on the back of the trans? The sensor and wiring can get damaged when they are forgotten or caught when pulling the motor out of the car. So it will be pre-existing.
The ESP should go out once you are driving again. Just hard lock left and then right. Ignition off then restart. ESP will stay on if the steering centre has been changed. A normal workshop will have the programme to reset it. (2 minutes) Don't worry about it yet.
Back to the cooked sensor. Yes I am saying that you have 3 connections. ---
negative / chassis (pin 1)
signal out to PCM ( centre pin 2)
+12v (pin 3)
The sensor can be cooked if either negative or +12v is applied to pin 2.
However, an internal fault inside the sensor will effectively do the same thing.
I'm not into coincidence. The thump you gave the car is responsible for this drama. Something was already faulty and shifted about.

I'm heading down there in an hour or so to put this mits sensor in. Also on the busted one on the pickup it's expanded protruding and has been touching the internals
-
Just came to mind. Did you check under the car to see where you made contact? That may give you a clue.
Did you hit the transmission pan? There are internal connections that have been known to cause problems.
That said, they do not appear to be connected to the sensor in a way that it would cause it to fry. seems like you are heading in the right direction.
Good luck

No it was the engine cradle that struck. I did get under for a look, looks like the tow hook, not a mark on the trans.
Anyway, the sensor out of my F4A51 trans is in and 100% operational. Saw no evidence or issue with the connector or harness. The input sensor from the mits the connector is oriented different but still could be installed and used which I may go ahead and do in the future but for now juts saved $90 keeping that bit. :wink:
As far as the errors, The ESP eventually went out, doing the lock to lock bit did nothing and the engine lamp extiguished too whilst doing a 10min drive, now back to waiting on my alternator clutch pulley, hopefully monday

Finishing touches, I just connected a basic ACTRON scantool up and sure enough there was a code stored, 0722 - output speed sensor no signal.
Boy I wish I had thought of this for the Mrs to bring down yesterday .
Cleared the stored fault code and has remained clear.
-
The dash display flicker has continued since fixing this. Not related, I've traced it to a worn or dirty drivers door ajar switch

I hate being wrong but the flickering is back and the door switch doe not seem to have an effect when wiggled.
starting to think faulty display or bad earth.

So time to review this again. Output sensor going well.
Holiday time so off to cairns. Day 1 no dramas to Mackay. Day 2 80k out of townsville , bang, harsh shift to 3rd forth lost. I know what this means limp. I don't understand why a fault light does not come on.
Here we go again. Last time it went neutral this time turning He car off i get 1st back but triggers limp Once it starts to shift.
So what's going through my mind plenty.
I'm already predicting shaft speed sensor and input this time ad i did the output a few weeks ago.
On my desk at home lies the other Mitsubishi sensor I was wondering if I should fit just in case buy decided not to, what's the chances. ?
Well very likely as it turns out.
Also on the desk my multimeter and scantool both I was also considering packing.
Stuck in Townsville in the heat i purchase a bluetooth obd2 tool and use the phone.
Sure as hell input sensor open cct.
Multimeter confirms.
Of course these are fitted to about 7 hyundai an kia models over the years. But do they keep any? No.
Limp for 400k to cairns. On order $200 more to follow

Struggling to get a signal at tinaroo.
The extra info I want to share is if you go back to the beginning of this thread I mentioned the input sensor connector falling off and having difficulty getting it to latch.
With the current drama I had plenty of time to get a good look. I can't physically get this to seat.
My conclusion on this is as I've also said before I believe this vehicle has seen extreme high temperatures.
The outer connector shell has is fact shrunk and nothing is going to allow the 2 to mate correctly. How it's manage to work thus far id luck but this does now explain why it's been coming loose and proving hard to connect.
Afaik they do not carry repair pigtails, only complete harness . If i can't find sn aftermarket connector my plan is to track down a Mitsubishi hatness to cut and splice. At the moment I have completely cut the sides off to fit this. New part won't arrive from Sydney until Tuesday afternoon.
-
Lucky you are handy on the tools. Would be a bigger money pit for most of us. well done! :goodjob:

Could this "extreme temperature" be due to the sensor cooking?
I spent two weeks during a humid summer in Darwin and concluded that the no speed limit on their highways was for health reasons...to aid rapid evacuation to a bearable climate. :p Even so, I cant see how the outside temperature could sufficiently exceed the engine bay temperature and cause the damage or various faults you are describing.
I would be looking for an intermittent short in one of your wiring looms.
Could be insulation chaffed on a metal edge or melted during the sensor burn out.
-
No signs of burning or heat on the input shaft sensor. There is evidence of bluing around the contacts but I suspect this would be due to the connector not being seated correctly and the weather seal being compromised.
No evidence of burning at the connector end of the harness, no corrosion, no evidence of burning or melting on the connector body.
The way I'm looking at this is like mr shrinkies. I don't think 2 weeks in Darwin would do anything.
I'm thinking along the lines of a few years in temps over 40. All the door window seals are blistered and cracked, the gear knob the chrome finish completely gone, leaving the plastic under yellowed and full of hairline cracks.
I've been in the Darwin too for several years and driven up the middle in other vehicles. Certainly never seen a connector shrink. To the naked eye it looked normal however once you tried to fit the sensor it would not remain in the guides, twisted and pop out of position and was about 3mm shy of being fully home..
I even removed the silicon seal thinking that may have been obstructing.
To me the top portion had shrunk and become tapered.
The sensor is close to the trans oil lines which may contribute to extra heat too.
Either way it had changed shape and did not fit, and a very strange situation.
No evidence of chaffing and the harness appears good, no evidence of excess current or melting of the individual wires either.
I'm confident once I reterminate and replace the sensor this should be the end of it.
But for sure if it continues after this down the track I'll be back here discussing it.
Not knowing the history or travels of this car also makes it guesswork too but the only thing I can think that would affect plastic is this way would be heat or solvents and I very much doubt it's solvents. Looks more of a gradual thing has happened.May be one of those one in a million things.
I've cancelled the parts order too. The other Mitsubishi sensor i left at home is going to fit and being expressed up to us.
EFI Hardware in Melbourne have the connector which is listed for an EVO camshaft sensor connector.

(https://www.efihardware.com/images/medium/6143/Mitsubishi-EVO-Mivec-Cam-Sensor-3-Pin-Connector.jpg)
One other thing , this sensor has no markings at all which makes me wonder it's not the original as the output sensor had kia/hyundai markings plus the part number.
-
Yes quite possible that it is not original. They are a Hall effect transducer that most cars use. You will find that you can interchange them from say, cam sensor to crank sensor role, just to prove a fault.
Unknown history is a problem. I have a D40 Navara that I call 'The Apocalypse' that came to me that way and with motor partially stripped.
Irrespective of the fact that they have a pig of a motor made by Renault, I did not suspect that it had a turbo that leaked volumes of oil into the intercooler. I found that out when the tacho red-lined and the crankshaft blew out the bottom of the engine. :whistler:
Better luck with your known unknown. :)
-
Happy to confirm the connector mentioned above is 100% correct for the harness repair.
My son sent the other sensor from our F4a51 Mits box and it too bolted in however there was yet another curve ball.
I dare say MIts set these up so you can't mistakenly connect the wrong sensor harness to either sensor. On the F4A51 they both sit on top of the trans however on the A4CF1/2 box one is at the very rear and the other one on the front right next to the fluid lines.
Anyway the locating guides on this particular sensor are offset compared to the other one which are centred and the ones fitted to the Hyundai.
A sharp blade and I removed the guides , it was then a snug fit into the connector.
Test drive and back to normal.
Hopefully I won't be back here talking about it again. :sweating:

CORRECTION.
Sorry, I just discovered something last night regarding the replacement connector I got. Turns out I'm wrong it won't fit the front sensor on the box due to the locating guide on the sensor being off centre.
I thought it was due to the mitsubishi sensor being different but I just did a powertrain swapover and the OEM Hyundai sensor also has the same off centre as the mits.
So in order to use it, the guides need to be cut off.

My light bulb lit this morning working on some research for connectors. Just realising in the Electrical manuals there's enough info to work out the connector types should one need repairing as in this case.
