    This is a 2002.

    Also the MIL light is on and the dreaded triple weird icon screen with a red right icon.

    The car starts and then stops.

    Nearest dealer is 50 miles away.

    Could this be just a loose connector somewhere?

    Thanks
    Dale

    Thanks.

    That is a quite a variety of systems covered by these codes.

    Does anyone see a common thread?

    The car worked fine until these codes.

    p0013 -- sure isn't p0103, which ties in with p0100, for MAF sensor problems?

    At least on Gen II, P0000 is a general fault code showing the car is greatly unhappy with something that someone has done to it. I got it once when I caused a short to ground of a wire going to the HV ECU.

    The C codes are virturally everything related to the hydraulic ABS -- wheel speed, master cylinder, etc.

    Look for loose/grounded/chewed wires!!!

    this may or may not be related... i had a bunch of low voltage alarms and such when an ignition coil went out... can any genI owners verify if a low output on the ICE side can effect a genI like it does a genII.. (my car still ran.. just crappy/slow) i'm thinking since you're has less power, it may not even try in that kind of "limp" mode.

    just a guess really. the advice above is good. a lot of earlier owners reported that mice and such have an easy time getting into these cars and love all the wires to feast on.

    I've checked all the easily accessible areas under the hood and trunk, any harder to reach places I should check?

    And it was p0013, some camshaft error.

    I think that you have a single component failure that has affected everything. Wheel speed sensors and brake fluid pressure readings are completely unrelated to CamPS and MAF, except for the fact that the car's computers are on a tightly connected network. Perhaps a ground point has come undone? This is the point where you need to break out the voltmeter and the service manual.
