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.
