My not so retro 2013 transit 2.2. diesel has been having issues. Power loss, massive power loss, but no check engine light or such warnings.
The AAA came and found codes in there for the fuel pressure regulator/fuel pressure sensor. So I'm researching the codes and where what is located and what a swap would entail to see if it is a diy job or a garage job...
P0089:00:2c CMDTCs Fuel pressure regulator A performance
P2539:00-2c CMDTCs Low pressure fuel system sensor circuit
Anyone on here that has any knowledge to offer?
I'd like to prevent a huge bill...

Looking at those codes I assume it’s a stage 5 (silver mesh in grille and drl’s)
When was the last time it had a fuel filter,how many miles has it done ?

Looking at those codes I assume it’s a stage 5 (silver mesh in grille and drl’s) When was the last time it had a fuel filter,how many miles has it done ? It's the first generation Transit Custom. Done about 95.000Km now and fuel filter will be from april 2016 or 2017. Car has done either about 45.000 or 32.000km since then. I can't remember for suere if the 2017 service I had done included the fuel filter, but I do believe so. It's set to have its next full service in april. It has had yearly oil changes in addition and service parts such as brakes replaced/serviced etc. From what I gather a fuel filter change is a pretty simple first test. Currently trying to find the components under bonnet, but not found them yet. Hoping to find a diagram of sorts... |

Located the parts.
Plan is to change the diesel filter and the pressure regulator.
Have only to find a procedure. It's fitted to the pump with two bolts, but I don't know if there's more to it than just undoing and replacing. It looks a simple enough task.
Apparently the fuel filter housing could do with a special tool to undo and do up. I was thinking using an oil filter removal chain type tool... or is that a bad idea?

The valve on the pump with two bolts is a volume control valve. It controls the volume of fuel sent to the fuel rail. The fuel rail will have a pressure control valve that controls the rail pressure. Each part of the fuel system can be tested for correct function with a different test. You could remove the volume control valve and check the fine mesh filter on it for metal particles. If there are then it’s new high pressure pump time. If you don’t have a in line pressure gauge then get it to someone who does. Proper testing will stop you spending money when you don’t need to.

They don't have a pressure control valve on the rail it uses the signal from the pressure sensor on the end of the rail to control the pressure with the valve mentioned above on the pump. Firstly though I know It's been very cold over there lately, we have seen issues with black deposits coming out of biodiesel in cold weather especialy on these where the filter is low down and gets very cold, the deposits block the filter, try a new fuel filter first.

If you replace the pressure regulator then the ECU will want to relearn the pressure values on the pump, something that will only be possible with a diagnostic scanner. |

I would not change or mess with the pressure regulator in the fuel pump.., Your going way to deep into it. Replace fuel filter first,then if it’s still the same you need to investigate the low pressure supply side first. Custom is prone to issues with the in tank electric pump,either the pump itself or bad connections in fuse./ relay that feeds it. This is more like the cause of your low pressure fuel code (if filter is ok) As for the tool,they’re cheap enough and using a filter strap will break all the plastic flutes off the filter housing. p.s. You’ll get the other fuel pressure regulator dtc if pump can’t control rail pressure properly,due to the low pressure side fault. |

Good point, the low pressure fuel pump fuse can get a loose connection with the bus bar in the fuse box (one to the right of the engine compartment as you look at it), my money would still be on the filter though.
Check the filter before buying a tool, some had a hex on the bottom, just get a proper hexagon socket not a 12 point one.

The fuel pressure sensor is on the end of the fuel rail which is top of inlet side of the engine. They're very common for causing problems. Whilst you've got it apart to sort that pop the injectors out and get them tested. Usually when they start having fuel issues they're pretty close to holing the pistons. We do loads of the bloody things, it's a shame really they're not a bad lump otherwise if they have regular oil changes.

Fuel rail pressure sensors don’t go wrong,the pressure control valve in pump and limiting valve in rail used to be a problem but that’s the stage 4 2.2 mk7 so in this case doesn’t apply.
Stage 5 2.2 in late mk7 and custom / mk8 transit fuel system is very reliable,problems with piston damage are caused by bad software maps and remaps,ford themselves did a recall to prevent piston cracking which was a pcm update.

That piston issue was indeed addressed on this specific car. Thanks for all the other suggestions... |

Thanks everyone for your input...
Fuel filter check is first, I'll check and see if it has a hex or not.
I can also try and see if the bus bar thing is ok, But looking it all over generally yesterday it all looks nice and clean. But I haven't looked for the bus bar specifically.
Will try and get a filter change asap and see from there...

As said above by several others, fuel filter change is the first port of call with those fault codes  And get a genuine one! Guy at work used to do fuel draining for a living (when people misfuel at the filling station) and the genuine Ford diesel filters have a better micron filtering...filter  Fuel filter would be up in the engine bay on the bulkhead on the right as you look in (on RHD at least) or tucked up just behind the front subframe |

Why do I keep 4 Euro 5 2.2 (2 FWD, 2 RWD) engines on stock then that are in rotation every 2-3 weeks because we get so many in with cracked pistons or the little end bushes smashed to bits. Only had a couple that have had remaps too. |

Because lots did plenty of mileage before having the later pcm calibration done,most have never even been updated since leaving the factory...
And lots are running about with 1 or more glow plugs inop which will hammer the pistons on cold start.
Bad Maintenence generally.
Either way it’s nowt to do with fuel rail pressure sensor...

Mine is under the car by the fuel tank. Mine also has a hex on the bottom so I should be able to undo it easily enough. I'll see that I get one and change it out and see what that does. Bus bar seemed fine as well. |

If you replace the pressure regulator then the ECU will want to relearn the pressure values on the pump, something that will only be possible with a diagnostic scanner. Is this really so? Cause that makes it a garage job really quickly... The ecm will learn new values based on how the solenoid is performing but it will also re-learn the new one over time, just take it easy for the first 100km or so and if in the unlikely event there are any strange combustion noises get it looked at. I'm very hopefull a filter will fix it though, as above use a ford one which are finer than some aftermarket ones and give better protection to the pump and injectors, the placement of these filters means they get very cold which caused numerous issues in the last really cold winter we had, later ones were heated. |

Well, for now I ordered a genuine oil and fuel filter and oil so as I'm going to be in there I might as well do both.
We'll see if more action is required... It's going to take a few days to get to me though...
