DTC P2263: Turbo Charger Boost System Performance
NOTE:
If DTC P2263 is detected, air flow regulation switched off, EGR valve closed, turbo charging regulation switched off and reduced performance.
Wiring Diagram
For wiring circuit and connector number, refer to “K9K Engine (Type 5)” in A-4 Engine Control System Circuit Diagram .
Detecting Condition
Status displayed on SUZUKI scan tool Detecting condition Indicator / Warning light operation
D1 At minimum limit Does not light
D2 At maximum limit Injection warning light (gravity 1 fault) light up
Troubleshooting
Check that the turbo charger is operating correctly, check the air intake system (blocked, etc.), check the boost pressure signal and check the gear number when changing gear.
Check the condition and connection of the boost pressure control solenoid valve connector.
Repair if necessary.
Check for the boost pressure control solenoid valve feed on “C97-2” terminal of the ECM connector.
Repair if necessary.
Check the condition and connection of “C47-3” terminal of the ECM connector.
Repair if necessary.
Check the boost pressure control solenoid valve for resistance referring to Boost Pressure Control Solenoid Valve Inspection:K9K .
Replace the boost pressure control solenoid valve if necessary.
Check the continuity and insulation of the following connections:
• Between “C47-3” terminal of the ECM connector and “C97-1” terminal of the boost pressure control solenoid valve connector
• Between “C54-3” of the main relay connector and “C97-2” terminal of the boost pressure control solenoid valve connector
Repair if necessary.
If DTC P2263 is still detected, replace the ECM.
After Repair
Deal with any faults detected by SUZUKI scan tool.
Clear the DTC.
Carry out a road test followed by another check with the SUZUKI scan tool.
