My bike started doing this last week (08 EGC w/38k), it started immediately after I let it sit outside thru a huge rainstorm. I had the handlebars all the way to the right where the throttle was pointing toward the ground. When I went to move the bike, water poured out of the right grip. After that, my throttle would stick and not return when I released it. Remove the sensor, more water and it's now starting to rust. Got a new one on order from Brandon Harley (104.00). gonna replace it rather than try and fix it.
