The newer cars have an IACV (Idle Air Control Valve). The older cars had an EACV (Electronic Air Control Valve).

Are they essentially the same? Just curious because I'm doing a swap.

I'm assuming they are the same since both will cause a CEL 14 if they are malfunctioning.

Thanks,

They DO perform the same function, but I'm not sure about them being the same physically, in their internal workings.

 

A bit of History: Before 92', the valve body located on the back of the intake manifold used to control idle was referred as EACV.

 

Very good question...... Ever since i swapped my d16y8 into my crx i have been having idle problems. I did not use the eacv from the crx, instead i used the iacv which is on the back of the manifold.

They both have the same number of wires, but i am at a loss. I sure am interested in your findings.
