Monitor Scantool Data
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.

a.

Specification : 1013hpa ± 100hpa(VGT actuator : approx. 76%) at idle

Fig1) Monitor "BOOST PRESSURE SENSOR" parameter on the Scantool at idle after warming engine up.

1013hpa ± 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%.
