IAC Actuator Position

[mrahiliftikhar]

What is mean by IAC Actuator Position.?
Meri Car Warm-up Engine per 850RPM pr IAC actuator Position 0.392% show kr rahi hai. But RPM stable hai. Jab Blower ON kro tb yehi value 3.561% ho jati hai aur AC Compressor ON krne per further kuch increase ho jati hai. OBD II Scanner pr Throttle opening 0%
Kia yeh sb normal hai.???
Agr theek nahi toh kia value honi chahy ideal warmup engine ki.??? Aur kese set kro

It seems like it's working as intended as long as your RPM is stable in all of these different conditions.

The IAC is the Idle Air Control. When the throttle is fully closed, the IAC allows a certain amount of air to pass through to keep the engine idling.

The alternator (blower fan speed increase) and the AC compressor are both items that load the engine, requiring more air and more fuel to maintain the same idle with the throttle opening at 0%. So the ECU asks the IAC to open up more to allow this to happen.

Me ne es liye pocha Bcz @Hassan1991 bhai kehte hai k idle warmup engine pr IAC actuator ki position 05-30% k between honi chahy aur ab meri 0.3% show ho rahi hai

Yeah I think he'd be right. The ECU will raise the idle and enrich the mixture when the engine is cold and needs to warm up, commanding more duty cycle % from the IAC.

Is there a problem with the way your car drives or warms up when you start it cold?

I think your scanner has a messed up PiD calculation

0.3% is incredibly fine resolution low.

Sir what will be the Solution.?

Use a different scan tool to see it, if your engine is idling correct you dont need to worry.
