Omega General Help / Re: 2.2 Dti Cutting out

« on: 17 June 2007, 14:26:46 »

so, after i put some clening additives in my fuel my engine sound a little better, but still some smoke.
I decided to change my pump and i drive 100km to a injection pump specialists.
Surprise, my fault codes changed, no P1220 some other with EGR and ....
They repaired it in half an hour something wrong in my vaccum circuit.
So check your vaccum circuit.
Now working perfect.

P1590 still present but it seems that its not important.
I have changed my broken piece.
Engine run well.
Still after a while yeloww light is on and some smoke appear.
Today I will receck my fault codes.
If P1220 will be find its seems that I have to change the pump.
Sad because its expensive.

I found out the cause for that noise in my engine.
A piece below cama axe was broken(i don't know the name for it)
It's possible that the p1220 problem was the cause for this because of unbalanced farce inside the engine.
However p1220 no longer present. When my car will be ready i will try to drive it feww km to see if come back.
P1220 is most likelly a injection pump malfunction.
Anyway the only explanation I have for p1220 dissapeareance is some injection cleaner i used.
So try to see if its not something in your tank and put some magic diesel in yor filter and let it run for 10 min.
If not my opinion is that pump have an mechanical problem.

i check my fault codes again.
P1590 remain but seems that its some high/low voltage error which don't influence the engine.
P1220 is gone but my mechanic said that probably will reappear later when is least expected.
Today we will check the cama axe to find out which causes that noise.
After, if we can solve that problem, i'll go to a center to check my injection pump.

I have the same problem with my 2001 omega 2.2dti(y22dth).
I could not go over 1500rpm, yelow light, a lot of white smoke.
I change filter, clean EGR, check turbo and nothing.
My fault codes P1590  and P1220.
They told me that P1220 is the injection pump, is a mechanical problem.
Suddenly without any intervention my smoke is not so dense, i can accelerate over 1500rpm, Is no longer yellow ligt on, but is some smoke when i push throtle pedal and i am hearing some noise inside the motor.
Mechanics told me that could be injectores, valves, axes or injection pump.
Monday they will disassemble my upper part and check those.
If not i will put it on a trailler and sent it 100km to a service wich repair injection pump.

NEW
No smoke, just when i go over 2500rpm.
No yelow light.
No stop on turbo, i can accelerate how much i want.
But still some smoke when i accelerate, much more then before the malfunction.
A very nasty noise come from my motor (frequency depends on ratation speed).
Some guys said that its axes, injectors, valves......
I am completly desoriented.

We dissasemble intercoler circuit. It's same oil inside but not much. So it's seems it's not the turbo. Anyway it's smoking now even if we put out the intercooler hose.
Everyone rise their shoulders and can not give me a diagnostic.
I spoke with some mechanics on phone (because they ar 100km away) and they said to sent the car because is the injection pump.
The simptoms are worst now : a lot much smoke and the engine is not smooth even at 800rpm. Some climping noise inside.

Filter changed and nothing.
EGR valve cleaned and a litle better.
New-in my turbo is some oil.
Same on entire intercoler circuit. Radiator(intercooler) very hot.
I suspect is filled with oil.
Still oil level is normal.
If disconected from intercooler I have no smoke but no turbo.
So the smoke is from the oil wich came into the intercooler circuit from turbo.
How did the oil get inthere?? Tomorow we will check the turbine.
Any sugestion?
Fault codes completly wrong.

Omega General Help / omega 2.2dti /2001  motor problems p1220

« on: 27 May 2007, 22:08:00 »

Hi,
I have an Omega from 2001 2.2dti (y22dth) and i have a big problem.
Few days ago, motor lose power, i can't go over 1500rpm, a terrible smoke come from exhaustion and my yelow light shine(service) on panel.
I tested with several programs b and i obtained this:
- OBD-II: P1220 Throttle Pos (TP) Sens2 Circ
- Autodata: P1220 Fuel Quantity adjusment control malfunction
I consulted several mechanics but no one is sure what is the problem. They sugested to clean tpsensor (Where is it?), to change filter, fuel pump or injection pump.
So if anyone experience the same problem or know what i shall do please help me.
