How To Check Wastegate Actuator. I then removed the hose from solenoid to actuator and removed the solenoid. You can test the wastegate itself for proper movement by applying vacuum with a hand pump directly to the line at the solenoid.
If you find the actuator rod has some movement try disconnecting the red vacuum line going to the WG Actuator and plugging it then give it a test drive. 2 Press the turbo actuator with your thumb. It holds vacuum fine my question is about the rod extension when boost is made.
Assuming good vacuum to the solenoid you will need to tee in to the line between the solenoid and the wastegate.
When boost exceeds the preset target the wastegate will bleed off any additional boost. 10 psi boost is still building and the wastegate actuator is pushing the wastegate flap open more. Then click on measuring blocksin the below screen. Lets first go over how the wastegate and actuator work.
