E0895801
1.
BPS visual inspection
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect BPS connector.
3)
Check if corrosion and damage in BPS terminal is detected.
4)
Check BPS mounting state, leakage at O’ring, clogged carbon at pressure detecting hall.
5)
Are the problems relevant to BPS found?
YES
▶
Replace BPS if necessary and go to "Verification of Vehicle Repair".
NO
▶
Go to "2. Check VGT Turbo charger and leakage in intake system".
2.
Check VGT turbo charger and leakage in intake system
1)
IG KEY "OFF", ENGINE "OFF".
2)
Check if VGT actuating rod which is connected to diaphragm of VGT turbo charger assy’ is at the bottom position.
3)
IG KEY "ON"., ENGINE "ON".
4)
Check if VGT actuating rod is pulled upward Approx. 10mm when engine is about to start.
5)
As accelerating and decelerating, Check if VGT actuating rod moves upward and downward.
6)
Check if intake air leak is detected at intake hose at acceleration.
(Check if intake hose inflates properly.)
7)
Are the problems relevant to VGT turbo charger and intake hose found?
YES
▶
VGT actuating rod does not work.
☞
If any problem is not detected after checking connecting condition of VGT actuator vacuum hose and VGT
actuator operating states(refer to "Component Inspection" of P0048 ), VGT actuator variable controlling part is
considered to be stuck. Replace VGT turbo charger in this case.
▶
Intake air leak is detected.
☞
Checking intake hose is not damaged and band clamp is fastened well, repair trouble causing parts.
If trouble causing parts are repaired, go to "Verification of Vehicle Repair".
