    Default Limp Home mode

    Hi all, cars been really playing up today.
    Its a 2.0 dti y20dth engine. 03 plate vectra.

    Basically for a while the car would cut out when idling randomly but not been too bad for a while.
    Now today it went into limp home mode this morning. pulled over, restarted and went off. Came on again so got into 3rd gear and dropped to 2nd to force the revs higher and it went off again.
    Then 2 min later its come on. really struggled to get home as i was some distance away. I removed and cleaned the egr. found a small split in tiny pipe from battery side of the engine.

    Went out. Lasted 5-10 min and came on yet again
    Don't have any diagnostics tools and not paying a garage to read them. Just stumped atm on what next I can check

    Have you checked all your pipes for holes?

    Been reading some more and I'm thinking it will be my crankshaft sensor to blame. But if this is gone most people say they loose the rev meter. Whereas mine still works.
    A while ago my rev meter did go a bit mental but the engine wasnt actually revving eratically. So I'm going to try and replace this tomorrow, fingers crossed.

    Anyone know if this is at the front or rear of the engine. Read next to starter on one thread and below oil filter on another and not had a look yet

    The crankshaft sensor is on the front of the block just above the sump and secured by a Torx bolt. You'll have 2 sensors nearby below it - oil temperature (looks similar to glowplug or sparkplug) and oil level (secured by circlip).

    There are 2 types - do you know which one you've got? See the link below - number 32 which has some cable attached and number 33 which doesn't.

    yes, i think 32 is for the y20dth and 33 is for the y22--- engine.
    I have the y20dth.

    Can the crankshaft sensor fail and send me into limp home mode and the rev meter still work though? It did drop to zero when travelling around 50mph twice but i presumed it cut out, so turned ignition off and on again to try and start it.
    Hope it is only that. really don't have time or money to be throwing at it atm. Girlfriend is heavily pregnant atm so can imagine it going into limp mode on the way to the hospital :P

    You may be right about the sensor - I have a 2.2 and it has the one with the cable.

    Your diagnosis sounds reasonable based on the symptoms but really you are shooting in the dark without checking for fault codes... Have you got any warning lights on?

    The only other cheap/quick things that come to mind are to check and clean the large plug on top of the ABS unit and also to check all the wiring plugs under the bonnet seeing as you have already checked the air and vacuum pipes.
