Turbocharger Control System

Turbocharger Control System

Refer to the system diagram to see a functional layout of the system.

Turbocharger Boost Sensor

This sensor converts charge air cooler pressure into an electrical signal that is received by the PCM.






Turbocharger Wastegate Control Solenoid Valve

This solenoid valve controls pressure to the turbocharger wastegate control actuator. The solenoid itself is controlled by the PCM. The Following information describes the ports on the valve and where the pressure flows when the solenoid switches the valve on and off.






Turbocharger Bypass Control Solenoid Valve

This solenoid valve controls pressure to the turbocharger bypass control valve. The solenoid itself is controlled by the PCM. The Following information describes the ports on the valve and where the pressure flows when the solenoid switches the valve on and off.






Turbocharger Boost Control Solenoid Valve

This solenoid valve controls pressure to the turbocharger boost control valve. The solenoid itself is controlled by the PCM. The Following information describes the ports on the valve and where the pressure flows when the solenoid switches the valve on and off.






Turbocharger Control System Diagram

The turbocharger control system controls the boost pressure and the response of the turbocharger. The PCM controls the turbocharger wastegate control solenoid valve (duty controlled), the turbocharger bypass control solenoid valve (on/off controlled), and the turbocharger boost control valve (duty controlled). The boost pressure is monitored by the turbocharger boost sensor.
