DTC P0047 VGT VACUUM MODULATOR CIRCUIT LOW
COMPONENT LOCATION
E2D3F84E
VGT Control Solenoid Valve
BPS & IATS #2
SCMFL6500L
GENERAL DESCRIPTION
E309637A
VGT(Variable Geometric Turbocharger) is the device which increases the efficiency of turbocharger at low rpm and lasts
optimum turbo efficiency at high rpm as varying the cross sectional area through which exhaust gas passes turbocharger
impeller. It relieves turbo lag at low speed and increse engine power generation.Engine speed, APS signal, MAFS and
Boost pressure sensor information is inputted to ECM. ECM actuates vacuum diafragm which controls exhaust gas line
as controlling VGT actuator duty to maintain optimum state of air compression.
DTC DESCRIPTION
EBA784B6
P0047 is set when "0"A is detected in VGT actuator control circuit for more than 1 sec.. This code is due to open or short
to ground in VGT actuator circuit, or open in VGT actuator component.

Fig.1) VGT actuator output waveform at 76% duty( (-)duty ). Duty decreases as boost pressure increases.
Fig.2) VGT actuator duty( (-)duty ) decreases as accelerating.

MONITOR SCANTOOL DATA
E08D4DA0
1.
Connect Scantool to Data Link Connector (DLC).
2.
Warm engine up to normal operating temperature.
3.
Turn "OFF" electrical devices and A/C.
4.
Monitor "BOOST PRESSURE SENSOR" parameter on the Scantool.
Specification : 1000hpa ± 100hpa(VGT actuator : approx. 76%) at idle
Fig.1
Fig.2
Fig1) Monitor "BOOST PRESSURE SENSOR" parameter on the Scantool at idle after warming engine up.
1000hpa 100hpa(approx. 1 atm) is correct value.
Fig.2) VGT actuator duty and boost pressure at acceleration is shown . If boost pressure rises and reaches certain value,
VGT actuator duty stops to drop and keeps steady. Releasing accelerator pedal at this moment, VGT actuator duty
drops to approx. 45%, then if RPM drops to idle range, duty returns to 76%.
