    Code 41 Speed Ident Sensor. What The Hell?????

    eerrrrrm last night me and tufty were in his veccy turbo C20LET MOTRONIC 2.7and the ecu light came on....... he quickly checked the code and it was 41.............. which is a bit strange as according to the code list, it does not have a code 41.......... any ideas anyone......... apparantly 41 is the speed ident sensor.......... we presumed it would be the crank shaft sensor can think of anything else but thought it would be a good idea to ask on here........????????

    I think you'll find that it is the "1st gear Ident Switch."

    This may mean that the wire that senses first gear on the box has come off / is broken.

    Management code 42 ??HELP??

    I know it refers to 42 but it may still be of use.

    Also have a look at this:

    I would have thought that it would be connected to the Engine circuit bearing in mind the sensor is there to control the boost in first gear (I think).

    Find the wire at the front of the gearbox (near bottom) and make sure its attached correctly and that the wires aren't cut etc.

    If you like you can cross the wires together to remove this limit and see if this helps.
