DTC P0299 TURBO/SUPER CHARGER UNDERBOOST CONDITION
COMPONENT LOCATION
E22A62B7
VGT Control Solenoid Valve
BPS & IATS #2
SCMFL6500L
GENERAL DESCRIPTION
EE6DEDEF
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
E9634186
P0299 is set when real boost pressure is much lower than target boost pressure for more than 12 sec. at above 1750RPM
and 22mg/hub of fuel injection quantity.This code is due to poor connection of VGT solenoid valve vacuum hose, vacuum
leakage, clogging, VGT turbo charger component failure.

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
E17E5543
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%.
