Ford transit fault P0299 (1 Viewer)

[nigglynelly]

I am currently out in the van but whilst driving here the engine malfunction light came on. It continued to drive as normal but it did loose power on a hill so I pulled over and stopped the engine for a few minutes. When I started it again it seemed fine. The same thing happened a few weeks ago so I took it to the garage and they said the fault was a turbo charger under boost. They reset it and thought it was a glitch as they couldn't see anything and also said it needed a good run.
I'm supposed to be going to another site further from home later this week but I'm worried I may cause danage by driving it. The options are continue as planned or return home and go to the garage again. Any advice would be appreciated.

Thank you. I've had a look but I'm not technical enough to really understand it. Is it an air intake problem?

Must admit i haven't got a clue hopefully somebody who knows will see your post

You don't say how old your vehicle is but the most likely causes are in the following order
A leak in the pipework between the turbo and the inlet manifold but this should also be easy to find as you should hear the roar of leaking air pressure compared to how it used sound
The variable vane turbo actuator is stuck causing low boost pressure. This is not easy to check but will need the operating arm rotating to ensure it's not seized (common when engine not used for weeks at a time)
The EGR valve being stuck open again causing low boost pressure. Can be stripped and cleaned but usually needs replacement for effective repair
You will probably save time and stress if you get a good diesel mechanic to look at it if you are unsure what to do

I found this for transit generic P codes

P0229 FORD - Throttle/Petal Position Sensor/Switch 'C' Circuit Intermittent
Repair Importance Level: 3/3
Repair Difficulty Level: 2/3

Possible causes
Faulty Throttle Position Sensor (TPS)
Throttle Position Sensor (TPS) harness is open or shorted Throttle Position Sensor (TPS) circuit poor electrical connection

Put simply.......Throttle position sensor tells the engine management computer how far down the pedal is then signals the injectors to shove more or less fuel in.

You need a stealer to check the code fully.

Thank you. It's a 2009 2.2. Is it still ok to drive or will I cause more damage?

 

[pappajohn]

Bugger, just noticed that's p0229, not p0299.

 

[Stretto Boy]

Looks as if it's the turbo. This may help. Good luck getting it sorted.

Blocked air filter?
Sticking waste gate?

 

[jonandshell]

Or drive it like you stole it for a few miles and see if it sorts itself out!

 

[nigglynelly]

Thank you for your advice, I'm taking it to the garage tomorrow so they can have a good look at it.

Italian Tuneup needed, thrash it hard for a few miles of hard work, probably a load of carbon build up in the EGR and turbo pipes, Stuck wastegate also a possibility.

 

[nigglynelly]

Thanks for the advice. What's an Italian Tuneup?

Thrash the bejassus out of it

Oooops sorry I'm being dumb. You just described it.

Thank you to all those who responded. The van has been to the Ford garage and the diagnostics say that it's the actuator that's the problem. It's booked in next week and they are going to send the offending part off for a repair which is apparently a much cheaper option than a new one.

Not sure if it helps, my Vauxhall astra gets a turbo actuator fault from time to time. It is a small vacuum pipe that has disconnected that is the culprit, to fix it, I simply reconnect the pipe and clear the fault code. Could this be a similar issue on the Transit?

Thanks for that. The trouble is I'm not at all technical but I would like to check it out. Can you tell me where I would find the pipe please?

 

[nigglynelly]

My local trusted garage has recommended putting 2 bottles of Forte diesel turbo cleaner in a full fuel tank then driving it carefully for a couple of hundred miles. He think the vanes on the turbo may have carbon build up on them which is causing the problem and that this is worth a try before going to the expense of repairing the the actuator.
Have any of you had experience of this product or have any additional advice on using it?

 

[DanielFord]

Thanks for that. The trouble is I'm not at all technical but I would like to check it out. Can you tell me where I would find the pipe please?

Can't help precisely, but if you look on the exhaust side, the turbo will have an actuator. There are normally 2 thin black hoses going into it, these are vacuum hoses, the idea being that as the vacuum increases the turbo is actuated and boosts the power.
They have little plastic or rubber connectors, just push them in. Do this when the engine is cold, the turbo gets very hot.

The ford 2.2 has a modulator attached to the body of the turbo housing which moves the variable vane arm. You should not be able to move the actuator arm at any time as the modulator is a solid state unit requiring a set voltage to move it. The more likely cause is the MAP sensor located in the inlet manifold is gunked up. This sensor monitors the boost pressure reporting back to the EMS which in turn controls the modulator on the turbo.

Below pic shows the modulator on the 2.4 duratorq engine which is the same as the 2.2. These modulators have suffered issues in that the wiring harness which routed over the engine suffers from stretching and heat damage. This was the case below and a harness extension was fitted to alleviate the issue from re occurring.


Below shows the location of the MAP sensor on the inlet manifold



Once the MAP sensor has been removed you can see the sensor end is gummed up by exhaust gasses/soot courtesy of the EGR valve.



A quick blast of carburettor cleaner will remove the gunk prior to refitting.

As to the throttle pedal dtc, unplug the accelerator pedal harness connection and check for damage. These units tend to have two states of existence, they either work or they don't. If you can get access to a diagnostic tool then you can see in real time what the readings are when you press the pedal which also will confirm if the issue lies there.



hTH.

Thank you so much for the very helpful detailed replies and photos. I will certainly check it out tomorrow.

I can't see how burnt exhaust gas can clean a turbo or EGR valve.
The cleaner will get burnt along with the diesel producing soot and pollutants.
A bit like washing your hands while wearing rubber gloves.
In my opinion....Just a bit of clever marketing for those who think it works..
