    Lightbulb Camshaft Position Sensor Replacement - With Pictures - 02 Deville

    The good old SES light came on, ran the onboard diagnostic program and discovered the car was throwing the code - PCM 0340 Camshaft Position Sensor.

    Car kind of started stumbling a little bit when I tried to start it.... So I ended up turning to Ebay for a new camshaft position sensor, got one sent out and it didn't work...
    So I ended up going to the dealer and paying the $105 for a new OEM unit... Also picked up a new electrical connector that plugs into the camshaft position sensor as the old one was weathered significantly $35...

    Step 1
    Arrow points to the coolant tank, remove the two nuts holding it in place, remove one plastic bolt, and unplug the electrical connector from the bottom.

    Step 2
    Carefully twist the coolant tank off to the side and out of the way. Once it is out of the way it is fairly easy to access the camshaft position sensor!!

    Step 3
    Remove the 10mm bolt that is on the housing of the camshaft position sensor, sensor should just pull right out, remove the electrical connector from the sensor.

    Step 4
    Look over all the wires for frays and damage, plug the electrical connector into the new sensor, put sensor back into the block, insert 10mm bolt, put the coolant tank back together...

    This was a really easy fix, if you can change your own oil, you can do this - I did it today with a broken knee in about 1 1/2 hrs. ....
    Good luck and hope this helps, the dealership prices are borderline illegal, so this will save a little coin!!

    Picture of one happy Cadillac!!

    I'm going to move this to Cadillac Tech Tips as it applies, with slight differences, to just about any Northstar CMP replacement. Thanks. I'll also leave a permanent redirect.

    FWIW, The CMP is bolted into the front (passenger end) of the right (rear) cylinder head directly in front of the exhaust cam sprocket.

    Good contribution!!! Not a hard job and havent seen after market sensors fail any more than the OEM so save the $ like you did.
