P0118 Engine Temp Sensor fix
Posted something similar in the tech sectionbut this deserves exposure. Something you can check beforeyour bikethrows a code.
I Spent the weekend with my bike throwing codes.
The first thing I learned, from this forum, is that you can retrieve the codes on 04-06 with the odometer of the bike. Directions on how to this are posted here:

Did that. Code"P0118 ET Sensor Voltage Open/High EFI."
(Engine Temp Sensor).
Cleared the code, rode for awhile &I got the code again. With visions of my bike on the trailer, battle with the folks at power commander(assumed it was the pcIII causing it), and my bike down for a week or two.
I called my local tech today. Told him my problem. He didn't even have to look it up. Said he has seen several with the same problem... he advised that the engine temp sensor is on the left side on the back of the front head, behind the horn. It has a rubber boot. The boot makes it hard to secure the electrical connector. He said give it a light pull, if it comes off, the connector wasn't pushed all the way in at the factory and it's worked its way loose.
That was the problem. You have to pull the horn off to get at it well enough to secure the connection but a 5 minute fix. Knowing this may save a few folks some grief. Something to look at the next time your tinkering with the bike....
