Hi

Can anyone tell me where the air intake temperator sensor is on a Ducato van 2.3 2010, getting an error code of p0095

Also where the turbo boost sensor is located, getting an error code of P0235

The van runs perfectly except for the error codes and the cruise control now does not work.

The van went in to a local garage to replace the defective throttle valve

Now I get the two error codes and no cruise control, garage is not interested...

Thanks

John
 
Hi,
Don't know the specifics of your engine, but on some Fiat engines e.g. 1.9 16V mJTD the pressure sensor and temperature sensor are combined in a single unit. It's possible the garage did not reconnect it. Have a look around the back of the inlet manifold. If the ABS is OK but you have no cruise control I'd start with the brake and clutch switches. What sort of garage was it?

According to the manual, the combined pressure/temp sensor is either bolted to the rigid pipe between the inlet manifold and the heat exchanger at the front of the engine, or on the manifold casting itself (depending on variant).

The sensor should look like the attached image, with a 4-pin connector.

Thanks for coming back, looking at the image you sent and the part for the van that I sourced, I just cant seem to find where the old part located on the engine (picture attached)

After the throttle valve was replaced along with the new wiring connector, I can now see a hanging 4 lead connector, the lenght of free loom is approx 12cm,(picture attached showing the lead connector and part of the new throttle housing), the garage is saying that it was never connected.

But if this is the correct lead, it presumably used to connect to something, it can only be 12cm away.

But maybe the garage are correct, but either case I still cant find the the combined pressure/temp sensor on the engine, unless it looks something totally different?

Appreciate any help

John

Hi,
The mating face and seal of that connector are clean so it's been plugged into something until recently. The sensor must be (or have been) in the area. It's unlikely to look significantly different. Is it possible that the garage fitted the wrong throttle body (is this a petrol or diesel? if it's a diesel then it's a shut down valve, not a throttle body), removed the casting with the sensor and fitted a hose instead? Does anything else look new apart from the "throttle body" The Garage has almost certainly done something wrong. Where are you located? maybe someone can recommend another garage.

2.3 engines up to 2011 build are likely to have the original design throttle valve which is replaced if necessary by the current version as in your picture.

Significantly this update also requires an adapter cable to connect it to the original loom. (look on ebay for pictures of throttle body and cable)

TBH the picture you've posted appears to shown the job halfway through; there is no inlet hose connected to the new throttle body?? My guess is that the connector shown is for the original throttle body i.e. it needs the adapter cable fitted??

You may well find that if the new throttle body is correctly installed and connected that the fault codes will clear (other posters on the forum have suggested that there is no specific code thrown up by a fault on the throttle body)
 
I agree with Crossingkeeper. Unless your photo was taken whilst still partially dismantled you are missing the air inlet hose between the heat exchanger and the throttle body inlet.

I believe the loose plug is the temp/pressure sensor connector though, rather than the TB solenoid connector.

See the attached photo. I have added two arrows which show the inblet hose that is missing in your photo, and the probable location of the temp/pressure sensor on the inlet manifold, which is what I believe your loose connector should be plugged in to.

Without the missing hose, you are only pulling in air at atmospheric pressure as there is no connection between the turbocharger and the throttle body.

In case it helps, this photo shows the adapter cable that should have been fitted with the new throttle body, fitted between the old TB connector (3) and the new TB solenoid (2)

Yes the inlet hose was not connected when I took the photos, I moved it away while I was investigating.

But after looking at crossingkeepers photo today, I found where the loose cable was meant to go and after much jiggling as the connector was buried deep under the new throttle valve, I managed to pop it back in. I was actually using a head torch, but when I reverted to a hand torch I could see much clearer underneath the throttle body...

So the garage had forgotton to reconnect it!

After a test drive there seems to be much more power and the cruise control works and all the error messages have been reset and have remained so.

But during the investigation I was also trying to also find out why I was getting a slight metalic sound from the engine bay when the engine was revved and during driving, this had only just started to happen I thought may be been linked to the 0235 error code and it is rather annoying. It's as if there is something metal rubbing outside of the engine, doesnt sound like its coming from the enging itself. I have used a rubber hose and listened to the alternator and air conditioning pump, but they seem ok.

After reading up, it was suggested that there maybe a fault on the turbo and to check that the turbocharger wastegate valve was working correctly.

It is quite difficult to get at, but I can see the pushrod and it seems to be firmly stuck, there is no movement at all, just wondered if this is something I should just live with or could it cause some damage at some point?

Appreciate the help that everyone is giving, I am planning on moving some furniture for a friend to Spain in the Jan and I just want to make sure the van doesnt let me down

I'd be askng the garage for a refund on the labour and never use them again. If they won't at least appolgise you should tell your local trading standards offiice. They may not do anything for you but if there have been other complaints or future ones, it is good information for them.

You should get the wastegate actuator sorted. A soak with penetrating fluid (Plus Gas or similar, not WD40) and some gentle wiggling may get it working. try a forum serch for info, most wastegate tubos are similar. The later variable gude vane types are a little different.
