Help Explaining The Difference Between These Parts

[Jap_Muscle]

Hi Guys,

Im after a few idle control parts for my car as it sems they have gone haywire. But im not sure if the items i have are actually the cor

Idle air control valve - 22660-01U10

Auxiliry Air Control - 23781-05U11

What is the difference between the 2? I assumed they did the same thing until i realised they were different parts.

Top pic is the air regulator.

It gives the engine a fast idle during warm up.

The 12V bi-metallic strip air valve gradually closes and by then your engine should be warm.

In my opinion not needed here is Aus. Had my cars with ice on them from cold start and the AAC would still control idle fine.

Just another item to go crazy and give you a high idle.

Bottom pic is the AAC valve. It controls your idle speed via a varying duty cycle signal from the ecu.

Both valves plumb into the idle air circuit upstream of the throttle body.

Depending on your car, the AAC may also do the idle bump-up for aircon or power steer actuation.

Thanks for the insight buddy.

So when ppl refer to the Idle Control Valve what are they referring to?

AAC.

Helps to stay with the Nissan convention for these parts, saves confusion.
