Here's what the nice guy at Autozone printed out for me:

P0116:

The PCM had determined that the input from the engine coolant temperature sensor changed too little or too much for currtent engine operating conditions.

Definition: ECT (Engine Coolant Temp) Circuit

Explanation: The Engine Coolant Temperature Signal is used for various systems in the vehicle.

Probable Causes: Check Connector and Wiring. Sensor open or shorted... replace sensor.

Now, I've EBAY'ed me a service manual, and I have got absolutely NO idea where this sensor is in engine compartment. Can anyone post a picture of their compartment with a pointer pointing right at it?

I had a Harley last year, and almost always most problems were tracable to something rattling loose, so if I just gotta tighten something or clean some contacts, just point me in the right direction.

Caio!
