    Hey,I have a 2007 cdti. Over the last couple of months the car has struggled to start every now and then. I have to keep turning it over longer than normal and it coughs and splutters. The EML comes on and when previously scanned it came up with crank sensor. It would always start after turning it over again though. I changed the crank sensor and it seemed ok but then 2 or 3 weeks later it did it again. The EML light stays on for a day and then goes out again.
    Any one had any similar issues?

    And does the EML come on because of a DTC relating to the crank sensor again?

    Where did you get the replacement crank sensor from?

    I am going to scan it tomorrow but I would say so, its doing exactly the same. I got the sensor from allparts made by bosch.

    Let us know what the DTC is then! But if it is the same (P0339?) then I guess it must be something related to the sensor, such as the connector or the loom?

    Timing chain stretch? Out of time?

    Have you actually seen chain stretch on a Honda I-CTDI cause this? My camchain was very stretched and making a horrible noise, but I never got this problem.

    Not as such but it is a possibility assuming the wiring and sensor are ok.

    I wouldn't expect a stretched timing chain to cause an intermittent starting problem and DTC.

    Hi, i have P0339 permanent cranksensor fault. Problem is when I replaced the sensor I checked the wiring and the condition and it's fine. And if there was a break in the wire or water ingress it would fail to start more often, it has never cut out when driving either.
    I'm a bit baffled

    The thing is if the chain was stretched it would be out of time all the time, and cause poor starting everytime. My car does this once a week, if that.

    Yes, it would. And the timing chain makes a horrible noise when it stretches. In any case, that DTC refers to an intermittent electrical problem and not a timing fault.

    How about other connectors along the wiring loom and also onto the ECU? Check them as well.

    I guess that the new sensor itself could be faulty, although I realise that this is unlikely.
