Where is the EVAP purge control valve located?
as to where it is , the location will be in the workshop manual or have a shop point it out to you. The EVAP Purge valve, on your vehicle, is located in the engine compartment. Yours is on the top of the front-right side (passenger side) of the engine. Just in case you need to know where the EVAP Vent valve/solenoid is located, it is underneath.
What are the symptoms of a bad idle air control valve?
Signs of a Bad Idle Air Control Valve
- Common Problem. Because an IAC valve controls air going into the engine only when the throttle is shut or almost shut, these are the only two times you're likely to ...
- Classic Symptoms. Classic symptoms of a clogged IAC are a rough or unsteady idle, and stalling if the valve passage gets too clogged or the valve fails outright.
- Less Common. ...

What is the IAC valve?
The idle air control valve (IAC) is usually connected to the throttle body next to the intake manifold. Consequently, it is the engine control unit (ECU) that manages all the functions of the valve. Based on the information it receives like engine load and temperature, it will change the speed of the idle accordingly.
What is the idling speed of a rotary valve?
In the event of an electrical fault, a spring maintains the rotary valve in a fixed position. As a result, the idling speed is increased to approximately 1200 RPM. The (ECM) incorporates a self-learning system, which enables it to learn the ideal idling speed. Because of this feature, the (IAC) valve is not adjustable.
What happens when a valve goes bad?
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. Since less air will be going into the engine during its idle state, the car will react by shaking profusely.
