My Idle air control valve stopped working about 1 month ago, I noticed that it didnt do the ticking that it usually does and when I accelerate, I hear this kinda fast sounding grind coming from that area(not the transmission). I replaced it with a working IACV and that one doesnt work, the exact same thing. No CEL and the engine seems to run ok....

Any Ideas?
Does anyone know what fuse or relay/circuit or whatever powers and controls the IACV? Maybe that burnt....

I have no idea what it could be, any help is much appreciated....

 

ANYONE???? I cant be the only one thats had this problem....
