Staldantes Posted December 13, 2016 Share Posted December 13, 2016 Trying to diagnose poor Turbo response on my Focus. I have found little information after extensive google searches. Can anyone explain normal wastegate motion from the actuator? When the car is off the plunger is 'in', starting the car creates vacuum and then pushes the actuator extending the plunger 'out', and I assume closing the wategate. The Turbo solenoid (beside the EGR solenoid, green top) then detects the pressure change at the correct rpm (2000rpm?), reducing electical resistance and opens, disapating the pressure, and opening the wastegate (plunger on turbo actuator returns 'in'), enabling the Turbo action. Is this correct? I really need to know if the actuator needs to retract or extend to fire the Turbo. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
