    02 M3 S54, P0012, replacing intake cam position sensor

    In order to access the cam position sensor I need to remove the air intake manifold which is the problem. Iíve disconnected everything required to remove it from the throttle housing yet it wonít budge??? Is there something located underneath that still has to be disconnected? The EVAP vent valve and the vacuum hose have been disconnected.1B1494FA-1CCD-41EA-BF81-6C9E241CE5E8.jpgFC711074-ABEC-496C-A486-1FF01F7858E2.jpg249F722B-C458-43F5-AED6-D8CAF01E67D1.jpg

    Probably need to break the seal between the 6 boots and the throttle bodies. They are probably stuck.

    That’s what I thought, what would be the solution? I’ve tried liquid wrench but that didn’t work.

    I would use a tool like this. Carefully insert the end between the boot and TB and work it around as much of the circle as possible to break the seal.

    Thanks, hopefully Harbour Freight tools has such a tool. Just had shoulder surgery 2 months ago and the strength won’t be there for another 4 months, thanks again for a solution.
