    Where at the Alldata site are the tables of DTC codes? My 1996 Grand
    Voyager is reporting a code of 72 which isn't in the table in my 96
    factory service manual (the highest code is 71). I'm assuming that
    there was a later update to the manual that I don't have.

    Code is catalyst efficiency failure (P0420) in the 97 service manual.

    Thanks. Any idea how the ECM can tell that the cat isn't working?

    Under certain operating conditions (hot engine, steady throttle, minimum
    speed and engine temp and specific load) the PCM monitors the difference in
    switching rates between the upstream and the downstream oxygen sensors.
