so i found out today my coolant sensor is not plugged into anything. the wire just goes down to where the air filter is and sits there. i also get the anoying add cooland light and horn as long as the car is on. some one please help me!

 

Find the other end of the wire and plug it back in. It's brown/white and comes out of the harness somewhere around the right headlight.

 

i found the stupid little nub of a wire sticking out. the wire was directly under my air filter.
