How does the vias control solenoid valve work?
Shortened port length will result in improved engine output with reduced suction resistance under high speeds. The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to On/Off single from the PCM. The vacuum signal from the intake manifold is cut when the solenoid is off.
When does vias signal to variable intake air system?
When the engine is running at high speed, the PCM (powertrain control module, also known as ECM or Engine Control Module in other vehicle makes) sends the signal to the VIAS (Variable Intake Air System) control solenoid valve.
When to replace a variable valve solenoid ( VVT )?
Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. Once you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
When is the power valve fully closed on a car?
As the engine runs at low or medium speed, the power valve is fully closed. During this condition, the effective suction portion length is equal to the total length of the intake manifold collector’s suction ports, which includes the intake valve.

How to replace a swirl control solenoid valve?
The solenoid itself is very easy to replace, but difficult to track down. A few tips: Be very careful when removing it. It’s very easy to break either one of those solenoids, vacuum housing, or hoses. Remove the old one and write down the exact part number molded into the solenoid. Apply 12v to the solenoid when removed to makr sure it is stuck.
Why is my variable valve timing not working?
The passing of additional oil to the VVT gears is a possibility if the system is not working properly. This very phenomenon manifests itself in the rough idling of the engine. It is primarily because the engine’s RPM fluctuates as the VVT starts working.
