    fiat doblo

    Hi every body new to this, not sure I am using this correctly or not so excuse me if its not right, I have a bit of confusion with a trouble code on a fiat doblo 1.3 JTD, its giving me a trouble code of P0234 supercharging pressure signal fault . Has any one had this problem it seems to be intermittent!! the worse kind I know. just wondered. I would be right chuffed to get a response and a solution, I thought of changing the manifold pressure sensor .

    You need to do pinpoint testing , check harness, wiggle wiring while monitoring scanner and voltmeter. No real easy way to get around things. Maybe could check for intake pressure leaks with smoke machine possibly
