Has anyone here pin pointed the reason why the IAC valve cliks with the key on? I saw a thread on it but can't seem to find it any help is appreciated.

 

IACV Resolution

There ya go!

 

Tried it on 3 maximas, never worked.

 

yeh i read somewhere that your ecu screw isnt turned fully counter-clockwise

 

Thanks it worked like a charm finally no click click click!!!!!!

 

The IAC valve or Idle Air Control Valve clicks when the ECM has been put in diagnostic mode manually using the screw on the side. Unfortunately I didn't realized this until I had already replaced the IAC valve and saw someone mention it vaguely here on a related thread. When I read it, it jogged my memory of this and sure enough I go and turn it back fully counter-clockwise and the clicking stopped. Yeah, I felt like a moron. I will accept the humility though so that no one else has to go through what I went through. It's all good. : ) By the way, this place is awesome!
