OPERATION
l
The turbocharger waste gate solenoid is an ON-OFF type solenoid valve that controls the boost
pressure that is introduced to the turbocharger waste gate actuator.
l
Battery power is supplied to this valve via the MFI relay. When the engine control module turns
ON the internal power transistor, the coil is energized to release part of the boost pressure applied
to the turbocharger waste gate actuator.
TROUBLESHOOTING HINTS
If the turbocharger waste gate solenoid harness and the unit itself are normal, but poor acceleration
or other abnormalities are experienced, the
problems are suspected.
(1) Faulty boost pressure control system
(2) Poor connection of intake air hose
(3) Faulty turbocharger or turbocharger waste gate actuator
(4) Clogged exhaust system
