Description and Operation 1-39
Engine Control Components
The second type of turbocharger bypass valve is solenoid controlled and is integrated in the turbocharger housing. The operation of the turbocharger bypass valves that are solenoid controlled is similar.
The third type of turbocharger bypass valve is an electropneumatically controlled system, integrated in the turbocharger housing, that consists of a pneumatically controlled turbocharger bypass, a vacuum source from the vacuum pump, a control solenoid for vacuum and pressure, and the tubing.
Typical Turbocharger Bypass Valve (Integrated Solenoid)
Typical Turbocharger Bypass Valve (Pneumatic Control)
Turbocharger Bypass Valve Solenoid
The turbocharger bypass valve solenoid is pulse width modulated (PWM) by the PCM to control the pneumatically actuated turbocharger bypass valve. The turbocharger bypass valve solenoid supplies or vents vacuum to the pneumatically controlled turbocharger bypass valve to open or close the turbocharger bypass valve.
