How do I know if my boost control solenoid is bad?
Test your actuator with a mityvac if you have one, if not join Your vac pipes together from the solenoid. If it reads between 0.7 and 1.2 bar your actuator is fine.8 Nov 2010

What does the boost solenoid do?
In most turbo applications the boost solenoid is used to bleed boost pressure off the hose that actuates the wastegate actuator. This makes for a more responsive turbo and for much better boost control, not to mention higher boost levels are possible with proper tuning.6 Nov 2008
Where is the boost control solenoid?
In effect, a boost-control solenoid valve lies to the wastegate under the engine control unit´s (ECU) control. The boost control solenoid contains a needle valve that can open and close very quickly.
How do you check for boost leaks on a Focus ST?
Check your logs, look at WGDC Actual. If that number is at 100% the entire pull and you are seeing lower than normal boost pressures. chances are you have a boost leak. At Sea Level you should peak in the 22-24 psi range and then the boost should taper down toward right at 14psi at 6000 rpms.15 Apr 2020
What does a supercharger bypass solenoid do?
The bypass valve allows the excess air to be diverted back to the inlet of the supercharger and recirculated. This ensures that the airflow measured by the mass airflow sensor reflects the amount of air actually being consumed by the engine. Using a bypass valve helps improve fuel economy.19 Aug 2010
