I have a P0235 fault code on my 2007 Voyager 2.8 CRD. Is there an option of cleaning the BP Sensor, or should I replace it? I have been quoted about £60 through Chrysler. Is it specific to this model or are they in any way generic, as there are much cheaper ones online, but I don't know the part no. Thanks

 

Boost pressure and temp sensor, sits atop manifold. Not clear about your 2007 model as mines 2003. Are my pictures alike. Does your power cut down of hard acceleration and light come on.

 

search goole for the bosch part number on the sensor....you should be able to find a better price.

Also just because the the ECU has flagged a P0235 it doesn't necessarily mean the sensor is a fault. Diagnostic procedure can be found here

I'll have that info too tfb. Amazing what you can find on here.

 

As I've got same code problem as you, but I've managed to overcome it, I am interested if the boost/temp sensor is the problem. But my cars just passed the MOT today after a page full of repairs including all handbrake cables. So I may get back on this fault if weather permits. Unless you find it first. Would be ideal to try another sensor incase buying one is a waste of money.

 

For reference there are 4 wires on the boost sensor, DB, DB/LG, LB/PK and DB/YL.
DB is ground. DB/LG is temp return sensor signal. LB/PK is 5v Reference or input volts. DB/YL is Boost return signal. So as boost increases, voltage will either go up or down, computer notes this and fuels accordingly. So this is the test I'm going too do soon to see what happens.

Another answer to code on boost pressure is Turbo Actuator as this is what makes the boost of course. So like me check its operation by substituting a rubber hose to it and suck. Course hose may implode so need to use plastic washer hose with rubber connections. Think I'll still put my money on the sensor (went I get some).

 

Have replaced the Boost Pressure Sensor and still getting the P0235 code and the MIL comes on after about 2 or three miles. There is what I would describe as turbo lag when accelerating at about 40mph, the revs ahng at 2000 and then after about 5 seconds, it atarts to accelerate

 

Sounds like turbo problem as in turbo operating problem. Check hose for leak, they often split at connection ends.

 

Hi Jodel you had any luck. Interested to know Boost/Pressure sensor didn't solve the P0235 Boost code. I didn't have the Turbo Lag thou.
