Help...P1191-52 code

scotty84

Hey peeps,

I have a 2006 2.2 direct 47K miles
Car had MOT this morning and passed with flying colours, he even commented how clean and healthy the car was.

Then around 30 minutes after getting back from the MOT I took a drive to argos (4 miles) was in there for around 20 mins then drove for around 5 mins and eml light came on (spanner in car) and lost all power. I switched ignition off waited 2 minutes and turned back on and all seemed ok but 2 mins later light back on and car in limp mode, wouldnt go above 20-30 mph and not 3000rpm on full throttle.

So Opcom has given me P1191-52
Fuel pressure skips between 4600kpa-5600kpa and pressure feedback says 1.5-1.7 V........

I had the same happen to me 5 months ago but slighty different as the car wouldnt start for 5-10 minutes after loss of power last time. But Vx said it was code P1191 and replaced the fuel pressure regulator under recall and everything has been great till today.

So am I right in saying as the pressure is averaging the ideal 5000kpa its NOT the HP fuel pump and its the fuel pressure regulator again?
I have called vx before I managed to get hold of the opcom and they said if its fuel pressure reg they will replace free of charge (as they should lol)
but if its the HP fuel pump im looking at £570 fitted, so I wanna know a little more before taking in the car tomoz so they dont try and replace the pump for the sake of it lol.

The mate with op com coudnt help as he knows nothing about the 2.2 directs or vec c as he is a vec b guy lol

Cheers peeps

Well what a suprise.......

Called vx this morning, they said drop car off put we may not get chance to look at it till thursday and it will cost you £64+VAT for us to fault find.
I informed them I had a opcom session last night and have all the info they need to point to the FPR valve, but they have said they will NOT fit any parts unless they fault find themselves.

They then said that if it is a faulty FPR they will have to call vx HQ to ask if they will cover the costs of part and fitting or even cobtribute to it.....I replied 1..Its on recall? he said but you had it done a few months ago I then said well doesnt all parts and labour come with 12 months guarantee?....he said not on recalls as I said Mr Evans I will try and ask vx for a contribution or full costs, but I can only try.....But I still need to to a fault finding session even if you have the fault codes etc because that doesnt tell us the fault it just lets us know it could be this or that.

How did you measure the fuel pressure?

On the z22se engine (might be the same for z22yh) there is a valve just like a tyre air valve on the inlet fuel line that connects to the fuel rail. In my experience if you press the centre pin (as if you was letting air out) the fuel should shoot up and hit the bonnet. If this happens then it would suggest the FPR at fault.

just a thought if you havent tried this already.
