ford monde tdci 52 reg fault
Discussion
hi all i have a ford mondeo tdci 52 reg and it wont start when it is warm i have took it to ford they charged me £400 to fix it and it hasent been.
these are the fault codes that ford give me
p-2288 injector control pressure to high
p-0054 heater resistance (bank 1 sensor 2)
can any one help please.
thanks james

Are you sure the second code is right?
Thats the code for a defective cat monitor hego sensor heater circuit, and is only on petrol engines.
The fuel pressure code does usually come with another code.
It can be caused by poor connections on the wiring to the injectors, imv and fuel pressure temp sensors or even the components themselves.
Do you use good quality fuel?
A sticking IMV on the pump from bio diesel deposits can cause it. It also slows down the the injectors and can cause it from there.
Did the dealer carry out the IMV test on wds/ids ?

i have no tuning box fitted. and that was the code ford give me so it might be wrong i cant stand the ford dealers in hull. i have spent £5000 on the engine repairing it over 4 years. i had a tech test done last week ford told me what was wrong with it so i paid £500 for the work and they havent fixed the car. ford did another tech test the same codes came up as before and now they are saying to spend £1100 on the injectors but they cant be sure that it will fix it.
thanks
thanks
I wouldn't be in a rush to replace the injectors 
There is a series of tests that can be carried out on the injectors themselves which measure their leak off rates over differing periods of time.
The theory is that if the injector is worn beyond the systems correction capabilites the amount of fuel returning to the tank via the leak off will be greater and the resulting pressure drop in the fuel system confuses the system.
On the delphi high pressure system, if the actual fuel pressure exceeds +/- 60bar from the desired pressure, the system will shut down.
Another area to look at for random/temperature related long crank/no starts would be the Camshaft position sensor. Without that signal, the system can't determine the sequence of injection.
Re IMV, thats the Inlet Metering Valve
It's located on the back of the high pressure pump and it determines how much fuel travels through the pump, if the piston becomes sticky with gummy deposits from cheap or bio diesel it can reduce it's performance to a total non start condition. The same deposits also act on the injectors.
It may well be the injectors, but if it was me being faced with the prospect of 4 injectors at almost 200 quid a pop i'd want the results of every test possible.
A delphi dealer might be a cheaper option.

I would spend some time on the phone to try and find a decent ford dealer in your area, my recent experience showed me that they vary massivly.
One tip might be to find a newer ford dealership that has not had the franchise that long, I know it sounds strange but a clear pattern emerged when I had a problem. Maybe its becuase all there tech training was recent, or experience of other makes widens the knowledgebase.

I take it Im not the only doubter of ford technician ability? Im sure some of them know there stuff, but so far none of them have been able to answer questions Ive had.
For exmaple, in the cambridge EMG ford they couldnt even tell me about transient over boost. I dont even know if they knew what it was or whether it really existed. How are we supposed to have faith in their fault findin abilities when they dont even know about some basic features of the engine / turbo.
back on topic. I trust you went back to ford and demanded a refund for the 400 quid they charged for "apparently" nothing. Personally I would have gone ballistic.
Im starting to think that Ill be selling my car before the 3 year warranty is up
