The correct test is to remove the sensor, hang it in a pot of water with a
continuity or ohm meter on it and a thermometer it and raise the temp until
it trips. Of course the shop would simply stick another sensor in and if
that didn't work you'd get charged for it anyway.

It's not the temperature sensor. We did a test the other day where we
unplugged it. The alarm system gives two short beeps to alert you and
then stops. Running with the temp sensor disconnected we stil got the
other alarm after several minutes of running at 3400 RPM. When I heat
gun the thermostat housing where both the temp guage sender and alarm
sensor are located, the temperature is within a few degrees of the
thermostat (160 degrees).

The owners manual says that alarm trips are recorded by the ECM.

Starting to sound like a trip to the dealer :-(

Maybe a "platinum" dealer if I can find one.
