    Default Help required please!!!!!

    Hi all, my 2.0DTI 03 veccy is giving me trouble - AGAIN. This time when the engine gets just about up to temp the EML comes on and its runs noisy, like a tractor. No boost at all and ABSOLUTELY gutless. Carried out the EGR and inlet manifold clean which gave loads of power back and felt like a new car - until the coolant got hot!

    So, took it to local garage and the fault codes are:

    P0335 - Crankshaft Position A Circuit Malfunction.
    P0340 - camshaft Position Circuit Malfunction.

    Any ideas will be greatfully recieved please chaps and chapesses.

    Looks like you need a new camshaft and /or crankshaft sensor. Did the local garage shed any light on corrective action?

    Hi
    I know this is an old post but I have something very similar - BUT with mine it is the Spanner light that comes on.
    Which light were you talking about - I thought the EML was the light in the shape of an engine - the emissions light.
    I have the same 2 codes but only when it gets hot - car is extremely slow.
    link to my post :-
    http://www.vectra-c.com/forum/showthread.php?t=103554

    Also I have just read the Haynes manual and it appears that, unlike the 1.9 diesel engines, there are no Cam sensors on the 2.0 or 2.2 DTi engines - is that true ?
    I hope you did get your's sorted
    Cheers

    I got a Vec-B 2.2 DTI SRI and my crack sensor went down a few months ago, when it used to get hot (or normal running temp), it would go into Limp Mode and the rev's started hunting.

    The Crack Sensor or the Cam Sensor was diagnosed, BUT luckily I got awat with just the Crack Sensor.

    Are your rev's hunting at all? Mine sounded cr4p too and just wouldnt shift at all!!


    Bye bye Vec B

    I think you've been smoking too much crank

    I don't get any hunting - ticks over steady but it sounds like a tractor but completely gutless.
    Just had a look around the engine - changed cam sensors before on the Calibra X20XEV 2.0 engine but I can't see anything similar on this DTi - no vislble wires around the timing chain area.
    The plug and wiring to the crank sensor look fine.
    Has anybody seen a CAM sensor on the DTi - as I said, No mention in Haynes and not listed as a sensor in the Fuel & Exhaust chapter under sensors linked to the ECU.
    Looking at what Vaux-Man-G said (but Vec-B) - think my next job should be the crank sensor
    Cheers pfj

    I also added this to my original post :-

    I changed the crank sensor - easy to find on the front of the block under the oil filter.
    Hardest part was cutting off the old cable ties - did not want to cut the sensor cable.
    Drove car 14 miles yesterday and 20 today without any problems so far.
    Warmed up to >90C and under these conditions - the spanner would have been on with the old crank sensor.
    Cost £30 for Bosch part (Euro Car Parts trade account).
    Cleared codes with Opcom and so far - they have not returned.
    Planning a 50 - 60 mile trip on Saturday - fingers crossed.
    Still have not seen a cam sensor and it is looking like the crank sensor only has effect when DTi engine warms up.
