Behaviour during malfunction:
• Insufficient output
Detection item:
• Dismount the hose between the turbocharger blower out and intake flange
DTC set preconditions:
• Other than during regeneration mode
• Engine speed is 1600 min
-1
(rpm) or more
• Target intake air flow value is 950 mg/cyl or more
• MAF sensor is normal
• EGR valve is normal
• Intake throttle valve is normal
• Boost pressure sensor is normal
• Barometric pressure sensor is normal
• Coolant temperature sensor is normal
DTC set parameter:
• Boost pressure sensor output is below target level in high air flow operating condition
Engine warning light:
•ON
Limp home action by engine ECU (system action):
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
•EGR stop
• Intake throttle 100 % open
Recovery from error:
• Key switch turn OFF

1. Check the Air Intake System
1. Check in accordance with "6.[1] AIR INTAKE SYSTEM
INSPECTION PROCEDURE". (Refer to page 1-S320)
• Check if the suction hose of the turbocharger blower does
not come off.
• Check if the hose of the boost pressure sensor does not
come off.
