mercedes vito 110 cdi y75shut off valve

[diagnoza_auto2000]

Hello to evryone,i have one problem with one Mercedes Vito year 2000 engine 220 CDI.
Eror code :P1622 y75 shut off valve.
Engine its not go up more then 3000 rpm.

Anyone can help me where its located this y75 shut off valve?
When i activate from HHT shut off valve for stop engine,engine still running.

Thank you .

[kool_mi]

you must change the ecu edc 15

[diagnoza_auto2000]

Its the only solution?

[vanos batam]

Its the only solution?
alternator charge voltase????

[diagnoza_auto2000]

Yes it is 14V

[vanos batam]

TDC adn CKP are ok?

[diagnoza_auto2000]

What you mean TDC and CKP?

[vanos batam]

What you mean TDC and CKP?

top death censor & crankshaft censor..if are ok
may be ecu fault

[diagnoza_auto2000]

yes are ok the sensors

Some time ago I had problem with some Sprinter with same engine and EDC15 engine management system. Had changed that solenoid with no result. After checking all things, it's turned up to be ECU fault. Then I rang Mercedes dealer and asked about reprogramming ECU with software version with no fuel shutoff valve and van went to them. After they did reprogramming, fault was still there....was messing after that with that van and after reconnecting the ECU fault just dissapeared. So...it's driving nearly year with the same ECU with no problems.
Hope this helps.

Well m8 , if the error code begins active after ignition is on, you have to check wires, or ECU . If the error code which by the way could deleted only when the vehicle is warm and motor is working,
and the later appeared on again, I think the problem is in the high pressure pump

[weryo]

It is 100% the high pressure pump,Master Andrew!
He just need to do some tests and to understand it clearly!

Sometimes engine ecu fails,..but it is not so common!
The wires could cause the troubles but not so common too!
But the high pressure intake little 'piece of shit ' could make you very nervous ,swearing around all the oil /fuel companies!

I agree whit you Weryo.

[diagnoza_auto2000]

Thank you all for good answers,sow how i see can be Ecu or High presure pump.
How can i some tests to be sure wich is the problem exactly.
But for exemple :
I erase the code,and then the car its working perfectly,i can drive how much i want but if i stop the engine 2-3 times DTC will come again,EDC light too and car go in lip mode(no more then 3000rpm)

I use Star Diagnosis for comunicate withe the car,but its a 638 model and its working on HHT and you can not see there sow many thinks.
Thank you again

There are some files from uncle Robert. Not a lot, but hopefully some help. They are Microsoft XPS files, needs XPS viewer. Opens in windows Explorer.
This is not easy job. Quite difficult to suggest something. I would start from wiring checks and then from cheapest option.

hi,

if the motor is running, you take of the connection, from the stop valve.(its a 2 pins connection next the high pressure fuel pump).
if the motor stops, then i am wrong and its another problem, but.

i guess the motor will not stop.

if this is the case, youre return valve in youre high pressure pump is leaking back.

in this case remove high pressure pump and check the valve.
it`s in the intake where you connect the LOW pressure fuel line.

if cleaning wont help. renew high pressure pump.

i am pretty sure this is the problem, but not for 100%

[garageozcar]

i know how repair PM by eprom file

[daniel sg]

May be your thortle valve censor not ok.

[milanovic]

I get problems same before .
But only repair the alternator. When 3500 RPM it is 16 V.
Then 1000 RPM 13-14 V.

When i remove this conector,motor its stop .I have try this already.

[mercis]

you can delete this errorcode over 60 C
all electric wire and ecu OK.
open high pressure pump,and check little valve
for low pressure,
you want,i can send picture
100%

[mercis]

after motorstop,check ecu low pressure side
with this valve,blocking this,have your errorcode

[diagnoza_auto2000]

Ok sow i cannot understand why when i activate shut off valve from DAS engine its not stop...
I have good high presure pump here and put on the car for test and same result .

I erase the code and its working good,dtc its come again only when i stop the car and start again.

100% high pressure pump.
this valve,see picture blockt.
you can erase error,okay
after engine stop,check your computer low press side,
cant valve move.

[diagnoza_auto2000]

I already try with a good pump and same dtc come out.

There is a solution to reprog ecu with a hex without shut off valve?

[finixservice]

READ 5P08 AND POST HERE.

[diagnoza_auto2000]

Thanks,tomorow i get ou the ecu and read and post the dump.Thank you

[treo]

I have same problem on Vito cdi year 2000
I check valve wiring everthing ok
I simulate valve with a resistor and erase error with diag tool for several times and error disapear,car works fine for 1 month after that error apears again and disapear it self.
I think ECU is damaged.

I think at this ideea too cause its chep solution,what resistor you have put? Same value as the valve?

Thank you

So.....maybe let's get clear with this. Seems to Me we are talking about different things. In my opinion Fuel shutoff valve is bolted separatly on the engine with two pipes on it. One incoming, another outgoing. So...if You mean third piston shutoff solenoid - this stuff is bolted on fuel rail pump.
I might be wrong, but I'm talking about fuel shutoff valve.
There is a programming version without it in main dealerships and of course somebody can remove it manually from EEPROM.
I'm not so high advanced in this....sorry mate.

How i said before ,when i activate actuator for shut off valve ,engine its still runing .
Dtc is p1622 Y75 shut off valve sow cannot be the solenoid.
I have documentation from Bosch too and there shut off valve its with 3 pipes but that valve its new on the car too.
Bosch say that is the shut off valve but when i remove the electric conector in ecu come the fault boost presure sensor,sow its not the shut off valve in my opinion.


I am a little in fog...

[Larue]

That's a good one.... Have You checked on rail pressure pump for third piston shutoff valve? I guess it's not there.
Funny one.
Are You sure about vehicle/VIN number selection? It's might be worth to try another diagnostic tool.
To be honest.....this story sounds about the same as My nightmare with Sprinter.

[treo]

I think at this ideea too cause its chep solution,what resistor you have put? Same value as the valve?

Thank you
Around 10 ohms is value of rezistor.
Aceeiasi eroare 1622 am intilnit si eu la vito cdi
Dupa ce am verificat valva am verificat firele am verificat tensiunea pe valva ,dupa oprirea motorului pe valva apare 12v pt 3-4 sec.

Yes i am sure about vin ,and evrything its there i understand now ,cause i am not the mecanic i only was called for diagnostic and the boy who work on the car put me in fog because he say this car not have shut off valve, but have!

I will try to replace by a 10 ohm resistor,but by editing hex file will be bether.

Merci mult,

Thank you m8:congrats:

Thank you m8:congrats:

better way is to replace your ecu with good one and then will see if that is the problem or other ...

[diagnoza_auto2000]

Yes,sure but until now i don t find one for this car.

[diagnoza_auto2000]

I check now the wires and are ok voltage always 7.5 V even when i activate not arrive to 12V sow i think ECU have some problems

you have trouble inside the pump
you can me believe,i make 20 year "shit mb"
you can delete errorcode,after motor run and stop
coming errorcode back,
wenn ecu damage,you cant erase error.
this little valve must easy move,see picture from me,

[diagnoza_auto2000]

Yes ,but already try with another pump and same error code

[weryo]

was it easy to change the original high pressure pump with the other one?
Did you check the intake valve free movement of the other pump before installing it?

Another tip:
When engine is idling,please press/clip the intake fuel hose to fuel filter using clippers,...and wait for a minute!
If the engine is still idling ,..be sure your high pressure pump intake valve is blocked and it feeds from the return fuel .

The main idea of shut-off valve is to stop the fuel amount in case you are in accident and airbag system is activated.
Then airbag control module sends an emergency signal to the engine ecu to cut the fuel off,to prevent fire of fuel leakage or at least engine damage caused by overforcing.

That's why the software inside the engine ecu always checks the shut-off valve when you stop the engine.
If shut off function not working,..the engine ecu stops the engine by another way/injectors signal/,...and immediately registers the fault code P1622.

All these things are written in WIS and they are true!


As a lot of people here were written,...if ecu is faulty,..the fault code will never be erased,..and into your ecu you could see some blown diodes and melted area on the plate PCB near the connector.

Good luck!

[diagnoza_auto2000]

I will try to press intake fuel near the fuel filer and i report.
But how you said Ecu store the fault when i stop because shut off valve its not working,i replace shut off valve by one 10 ohm resistor and same think hapen.

I will check that diodes too,thank you m8

[weryo]

Probably your shut-off valve is working,..and you must have been checked already that ,....these had to be your first checks before asking for help here!
probably you checked the wires and ecu plate either!

But you say nothing about the little intake valve in high pressure pump!
Is it blocked or not?

The engine ecu always checks if engine is stopped by the shut-off valve or not,...and if not,...ooops,..P1622 and emergency mode!
No mater what you connect to the connector,..resistor,valve,..or something which could imitate it,....you will always get the fault code P1622 because the shut-off function was not accomplished.

Good luck!

Thanks man for your professional answers this wrilly help.
Monday the macanic will open the high pressure pump and will check the valve.They have changed before the high pressure pump but they are not sure about another if was good or not.
I am not mecanic i only help them with diagnostic tools.
Monday i will report.
Thank all for help:champions:

[mercis]

oh yeah,and erase over 60 celsius

[diagnoza_auto2000]

We have dismount from the car the high pressure pump and we can see the valve inside ,that mercis show me in picture.
How can i know if its bloked or not?

[mercis]

see my picture,valve must easy move

[diagnoza_auto2000]

Its blocked down my friend,how can i unlock ?

I unlock the valve inside the pump,now its easy move,and now car its stop when i press the fuel pipe,before car still running,sow good work.
But erroc code (shut off valve y75) is still there ,i erase and he come back after 3 times of stop the car.
Tomorow i change again shut off valve Y75 and i report.
Thank you

[loisicar]

im working to much on BMW mercedes

if Y75 is dammaged it stay dammaged and can not erase with star ,just erase and restart engine fault becomes or can not erase and EDC light apppear again
the problem is ECU , it take this shock when some wire from Y75 are shorcuted ,
replace EDC15 by another one
take care if you bring used one there is two kind of flash inside
one type with Y75 , other type without y75

[mercis]

flash without Y75

I change the ECU and car work good now ,sow ecu was failed.Maiby some cdi drivers inside are broken.
But i will not try to repair i find one from another crashed car and evrything is ok.
Thank you to all the persons that help me for solve my problem.

[weryo]

did you change something inside the used ecu?

[diagnoza_auto2000]

I put ECU ,immo box and the t5 from key from another car,cause i heard only like this its working..

[MarkPRP]

SWapped 24c04 chip to new ecu and all work ok!

I have this problem with a van I bought today, but it revs to 4500 so no limp mode!

Will inspect and report with finding!

[diagnoza_auto2000]

With another ECU,immo and t5 car come back after 2 weeks with same error.
Y75 shut off valve
Maiby we can find a pair dump immo+ecu without ELAB(y75)

[diagnoza_auto2000]

I reprog flash with dump without Elab,car start but run only few seconds then stop.
I found one DTC :
Control module not coded,i try to code with some Vito code that i have it from before ,but DTC remain there.

[DJAMY]

here is tested files
work perfect

check wires of y75 , when they are shorcuted , it will be source of your problem
this ECU is so fragile with shorcut especialy y75
take care

Thanks m8,you think i must virginise 24c04 too?

[diagnoza_auto2000]

Car start only 2 seconds then stop,i think dumpr from immo its need too.

Car start only 2 seconds then stop,i think dumpr from immo its need too.

I have a vito with burned ecu i have put a new ecu and code it with star but the car start only for 2seconds and it stops

It is saying control module not coded ?

Can anyone help me what to do ??

THANKS

[diagnoza_auto2000]

You not coded corectly,take a look on EPC and code exactly.
Do you change the wsp to?

[kaToo]

hi
i made it virging using immo killer
than i go to car and try start but it dosent crank
than i code ecu with star and car start cranking
Sometimes it start for 3-4 seconds than shut off

[ssilvviu]

I need Y75 removal (no elab) and codding to manual transmission for a Mercedes Vito.
Could you help me?
