P0335 ошибка ford transit

Hi all. This is my first post, shame it’s not a happy one. I’m posting his here in the hope that someone who knows more than me can point me in the right direction. My local garage suugested seeing an autoelctrician.

I have an 03 connect tdci with around 130k on the clock.

I have had an ongoing running fault for the last few months, glow plug light flashes followed by the engine cutting out. It’s steadily getting worse until now sometimes it wont start at all. Local garage read the codes and said it was the cam sensor which they changes twice. The first was from a motor factor the second a genuine ford part. Fault didn’t improve.

I got myself a code reader on ebay and read the codes then cleared them. Re reading them after it played up again. I got cam sensor P0340 twice and the cranks sensor fault codes. Installed a ford crank sensor and the problem still remains. I’m guessing it could be wiring. I called ford yesterday to ask if my van would need the updated connector for the cam sensor. they said no. Are there any other parts that can be at fault within these circuits to cause the problems. Or are there any common areas of wiring that break down. Seems a coincedence that both sensors/circuits are at fault unless they share some circuitry.

Anyone have any ideas.

Thanks Nevil

8/17/05 Poor power; delayed accelerator response and/or rough idle, engine hard or impossible to start
Poor performance Delayed throttle response Rough idle or hard to start and WDS checks reveal that either diagnostic trouble code (DTC) P0340 or P0335 is set, the probable root cause is a loss of signal from the CMP sensor. To rectify the concern, a new CMP sensor and electrical connector should be installed as required.
Due to various changes to the CMP sub-system throughout the listed products program cycles, it is necessary to make sure that the wiring loom side electrical connector is compatible with the CMP sensor in the event of a new CMP sensor being installed.

Thanks for the reply Paul. I had already found that one. That’s what prompted me to talk to ford about the connector upgrade. They were adamant that my van didn’t need this upgrade.

Is that written by ford? Are they saying the connector may need changing or a big chunk of the wiring. Not really sure where that leaves me. I was thinking maybe bad conection or bad wiring. I’m really hoping for suggestions.

Yes that was the TSB done by Ford

I does suggest the the connector may require replacing & was a fault identified by Ford

Since sensor has been replaced, then I would check the wiring as it appears to be an intermittent fault which is getting worse.

Thanks

This should help

2003-2006 TDCI Engine Sensor wiring diagram

Delphi ECU plug pinout Location Behind O/S kick panel below dash

C93 Plug pinout Location N/S in engine bay just above gearbox

C94 Plug pinout Location N/S in engine bay just above gearbox

Crankshaft sensor plug pinout Location back of engine next to gearbox (near VSS sensor)

I have no diagram for the Camshaft sensor plug although pins should be numbered on the plug

Nice one Paul. That should keep me busy for a while.
I have been told all sorts of things it could be. Some sound reasonable. Others look ridiculous to me. However I’m no proffessional. I am a little shocked at how differant technicians come up with such differant fixes. So far I have been told it’s the

Diesel pump
injectors
wiring
accelerator pedal
glow plugs
ecu
flywheel. ( mine has a single mass )
sender unit
fuel lines

Difficult to judge how likley some of these are but a good starting point seems to be to get to the bottom of the fault codes I’m getting. If it turns out that the vans brain is storing these codes when all the sensors/wiring are good then maybe the next step will be to get the pcm ( ithink thats its name ) checked out.

On a differant note. what would be the effect if the van had the wrong values for the injector codes. I looked at mine using F super and all four have the same codes stored. The codes are 0000 ffff 0000 ffff. I tried to correct them using f super again putting in the codes on tghe ring on each injector. All seems to go weel but after the proccess is finished and I start the van, when I read the injectors again they have returned to the values above.
I assumed that f super is too naff to perform this function but could it be a fault with the PCM. I guess it’s possible.

Thats a long list

I always read the DTC codes first, this is the most accurate way to point you in the right direction.
Clear the codes & see if the same ones are storeed again.

The Injectors you have are Delphi & should be coded to the ECU

I have heard the issue with the F-super not coding the injectors to ECU properly, Try doing them one at a time.

Please don’t send me PM’s, i can’t access them, when I try I get this:

can I just add this from the ford tsb on this concern

Check the vehicle build date. Is build date after 08/2002 for 2.0L Duratorq-TDCi (Puma) Diesel or 11/2002 for 1.8L Duratorq-TDCi (Kent) Diesel?
•YES — No CMP wiring loom side electrical connector update is necessary.
•NO — Go to the next step.
2. Check the colour of the CMP sensor. Is the CMP sensor grey or black?
•GREY — No CMP wiring loom side electrical connector update is necessary.
•BLACK — Install a new CMP sensor and CMP sensor electrical connector.
now as you have changed the CMP twice can u remember what colour the original one was?????

Thanks for you help guys.

Taz the one I took out originally was grey but I guess there is no garauntee it was the original one. How would I find out these detailS on engine model and manufacture date?

I haven’t had a chance to do it yet but does my plan to try and inspect and test the wiring to the two sensors sound about right? Is there any other way I can test the two circuits.

whats the registration number?, the engine will be a 1.8 kent engine, the tsb also relates to mondeos and transits which are 2.0
