    I assume your 2002 utilizes the MMDC module for controlling the digital gauges. There are several threads on diagnosing/trying to repair errant gauges.

    Your tach should be connected to the ignition coil. Check all the connections and make sure they are clean and making good contact. Try disconnecting the negative and reconnecting it. It may just be a bad gauge
