OM642 and P0237 code
Hi.
I could use some help please guys.
My Jeep has the OM642 engine. Check engine light is on and vehicle is in limp mode. Code reader gives P0237 'Turbo Boost Pressure Sensor Circuit Low'.
Is this likely to be a simple sensor fault? Is the boost sensor on the hose that exits the intercooler?
Any other issues that can cause this? Hoses from turbo all look ok and i can't hear any pressure leaks.
Any suggestions would be great please.

Hi.
Thanks for replying.
Recently fitted a new resonator and associated O rings so that should be ok. I will look at the hoses.
Can P0237 relate to low pressure in the system? Is it worth changing the sensor?

Checked the intercooler hoses and there is no obvious leaks, splits or oil stains that i can see. Have you any idea where the boost pressure sensor is? I found a diagram on the net that shows it down by the throttle body. I cant see anything. Part search shows it as a T shaped sensor.
Thanks.

Try OM642 sensor diagram - Bing images
Those engines had 100's of variations, so it will take some scrolling

Thank you very much for the link. I will scroll through them and have a look.
I know just what you mean by the variations, i looked at some pics of a om642 from a Sprinter and the difference amazed me considering they are the same basic unit.
