BOOST CONTROL SOLENOID / VALVE

The boost control valve

allows the ECU to control the

amount of boost pressure within the induction system.

Boost control is accomplished by pulsing the valve at

different frequencies (pulse width modulate) depending

on the amount of boost pressure within the induction

system. If the ECU determines that the targeted boost

pressure has been obtained, the ECU will trigger the

pulse valve so that a certain level of compressor

pressure is routed to the wastegate actuator. Doing so

activates the wastegate so that a proportion of exhaust

gas bypasses the turbine. The boost control valve vents

to atmosphere when building boost. If the vent hose

atmosphere is plugged, an underboost code will set.

If a trouble code is being set for the boost control valve

and the vent hose is not plugged, the valve can be

statically tested with a multimeter. Disconnect the

harness to the valve and ohm the two pins on the valve.
