BOOST CONTROL SOLENOID / VALVE

q
The boost control valve
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.
