Ducato (X250) 2.3 150: turbo boost sensor location ?

[Ridgeway]

Can anyone point me in the right direction as where I can find this ?

I have P0238 and P0238 codes which indicate low and high pressure faults. It seems reasonable to check the sensors cables first.

I would suspect the boot pressure sensor is reading correctly check the boot selonoid valve and make sure the vacuum pipes are not split it sits behind the bracket behind scuttle

Wizza what do the vacuum pipes look like ?

Are they connected to the Dytech 460 unit ? as these are black rubber pipes that are 4mm ID and roughly 8mm OD, both pipes are totally destroyed, could it be these ?

This is the Dytech B460 unit:

One of the pipes that comes off a T that has been chewed

Dytech is just the manufacturer but well done for locating the problem, a new length of pipe will fix your problem

I sits behind that unit but them pipes split can cause overboost

OK to close the loop on this. I replaced the vacuum hose (there are 3) and still got the same error messages. I then cleared them with an OBDII bluetooth device and it's all sorted now no more error messages and now the turbo is whistling away again.

Forgot to say thanks for the help on this, another great example of why the MHF subs are well worth it, saved me a fortune !!

PS: reading all the other "upgrade" threads does cost me a fortune though

Glad you got it all sorted
