    Can anyone tell me the difference between ECM and PCM. And where are
    they usually located. It would be an even bigger help if someone can
    point that out for my car - 2000 Hyundai Sonata V6.

    Passenger side kick panel in front of the door under the dash. Take
    the kick panel off to see it clearly. Called a ECU - engine control
    unit. Also TCU transmission control unit (mounted in the front
    consol under the radio)

    Just went and looked it up. Both ECU and TCU are under the radio (on
    the hump). Bottom one is the engine controller

    ECM stands for Engine Control Module. These modules control the engine
    only.

    PCM stands for Powertrain Control Module. These modules control both
    engine and transmission.

    Your car, a 2000 V6 Sonata, has an ECM located under the center of the
    dash as cselby has posted.
