How the Idle Air Control Valve Provide Smooth
Idling of your Car
2
The idle air control valve of your car generally
used to regulate the amount of air flow to the
engine at the idle state of the car engine.
3
For the fuel economy and safety of the different
parts of your car right idling speed of the
engine is very essential.
4
As it is controlled by the engine control module
and check the engine idle speed to control the
amount of air bypass the throttle intake plate.
5
In two idle setting, the minimum idle setting
allow the certain amount of air to pass through
the valve irrespective of the IAV valve position.
6
But the running idle setting is used to achieve
by the combination of the IAC valve position and
the airflow.
7
Throttle following
8
The main significance of the IAC valve is the
throttle following which is basically used when
you floor the car and close the throttle valve
suddenly.
9
In such situations, the IAC valve of your car is
open up temporarily and allow some air to pass in
it.
10
As a result, the compensate of the valve drop
suddenly in the air and allows the engine to
decelerate gradually.
11
High Altitudes
12
At the idle state of your car, the engine RPM
should be minimized and consider this scenario at
a higher altitude.
13
The density of the air is placed at less, and
normal idling setting. Then, the engine will die
down and face restarting issues due to less air
flow to the engine.
14
In these conditions, the ECM adjusts the IAC
value of your car in which the air flows through
it and the engine idles smoothly.
15
Keep engine running
16
If you find that the sensor in the IAC valve is
used to detects a drop in the idling engine RPM,
then it opens up and allows the air to pass.
17
As a result, when it will pass into the engine,
then it will eventually increase the RPM of the
car engine.
18
So, it's your responsibility is to prevent the
engine from stalling and try to keep the engine
warm and running.
19
Conclusion
20
If you find any types of defects in the IAC
valve of your car then it can lead to engine
running problems. So, keep the IAC valve in good
condition.
21
If the idle speed of your car is too low, then
the engine will stall or idling will be rough or
in case of high idle, the engine is overheated.
