LOCATION OF IAC

If you are standing in front of the car looking at the engine. It is at the right end (drivers side) of the intake manifold under where the intake air hose from the air filter connects. It is black with a white 3 wire connector.

electronic throttle control.there may not be an iac at all

Im currently having this issue, I looked in a Haynes manual for 02-06 camry and it doesnt register a IAC just a MAF (mass air flow) I bought some MAF cleaner and going to attempt it now, good luck
