How much is a idle air control valve?
The replacement cost of an idle control valve is anywhere from $120 to $500. The cost of the parts alone will be between $70 and $400+, depending on the make and model of your vehicle. The labor cost should only be around $50 to $100 because it doesn’t take that long to remove and replace the old idle control valve.
Where can I find the IAC valve?
The idle air control (IAC) valve is located on the throttle body of fuel-injected engines, where it works with the vehicle’s ECU to electrically regulate airflow to the engine to ensure smooth idling.
How much does an air control valve cost?
The average replacement cost of an idle air control valve is between $120 and $500. The parts could cost anywhere from $45 to more than $400, while the labor is only around $70. Of course, the labor cost really depends on the hourly rate of the mechanic.
What does an idle air control valve do?
In the not-so-distant past, nearly all cars had an idle air control valve (IAC). It’s a pretty simple device that controls idle speed by managing the amount of air bypassing the throttle plate. Some IACs are stepper motors, while others are solenoids.
What to do if your air control valve is out?
Start the engine and check IAC operation. Tip: Don’t start the engine while the idle air control valve is out. You should notice your engine runs more smoothly with a steady idle. If you continue to notice rough idling, talk to a trusted mechanic such as one from YourMechanic, to diagnose the problem.
What happens if the idle valve goes bad?
A normal healthy idle air control valve (IAC) will provide smooth idling in your vehicle. But if the valve goes bad for any reason, the idling will go from smooth to rough. A rough idle will result in intense vibrations forming whenever your vehicle is stopped with the engine running.
Can a bad air control valve cause an engine to stall?
Sometimes the engine stalling will happen on its own while other times, increasing the load on the engine will cause it to stall. For example, if you turn on your heater or air conditioner when you have a bad idle air control valve, then your engine will probably stall immediately afterward.
What are the signs of a bad idle air control valve?
Rough Idle. If the idle air control valve has gone bad and no longer regulates the flow of air into the engine, typically due to the IAC being stuck open, the vehicle will idle roughly. A rough idle is characterised by shaking, vibrating and shuddering while the car is on but not moving.
What is the function of the idle air control valve?
How an Idle Air Control Valve Works. The idle air control valve is a component of the internal combustion engine. The function of this valve is to manage the engine idle speed so that it stays within a normal RPM (revolutions per minute). For instance, whenever you stop or park your vehicle, the engine will continue running.
How do you check the idle air control valve?
One of the easiest ways to test your idle air control valve is to simply look at it. Check to see if the valve stems have dirt on them or if they are burnt. Check the valve opening on the throttle body to make sure that there is solid contact between the valve and the stem.
How do you reset your idle air control valve?
Try to clean out the passage way to the idle air control valve at the throttle body. Once the throttle body has been cleaned and the instructions have been followed, you can reset the idle air control valve by turning the ignition keys to the on position for 30 seconds and then turn the keys to the off position then on for 10 seconds and then start.
