    There is something wrong with the exhaust cam position sensor circuit and/or the exhaust cam position actuator circuit because the two aren't coinciding, that's what's setting the code.. You need a GM specialist to diagnose it and estimate for you.
    BTW: Going to the dealer and having the code erased and putting the light out doesn't fix anything..
    If you want to see a specialist, here's a directory link for you:

    Thank you

    Would this cause my brake lights to fail?
    Or my door locks or windows to malfunction?
    Why would filling the gas tank and topping it off turn the light out?

    Thanks Superbob
