My 2003 SE automatic, blows the #59 engine control 2 fuse 2 imediately. Checked ECU, DISCONNECTED ALL SENSORS ONE AT A TIME AND BLOWS NEW FUSE IMEDIATELY EVERY TIME. DONE VISUAL INSPECTION, unbolted the fuse block and checked under, finding that the white w blue stripe wire going to that location was very tight. I gave it some slack and noticed that the connection is very loose and wiggly. Could this be my problem, causing a new fuse to blow the second I touch it to the terminal?
I read that since it blows immediately, the short has to be between the fuse block and the engine control relay. Is this true?

 

Grab a wiring diagram and VOM and start looking!
