Overview Plan of Exhaust Turbocharging System

Overview Plan Of Exhaust Turbocharging System (Vehicles With Engine Code AUG, AWM)







1. EVAP canister
2. Vent line
- From gravity valve at fuel tank
3. Check valve
- For EVAP canister system
4. Turbocharger
- The charge pressure regulator valve and vacuum diaphragm for charge pressure regulator valve are part of the exhaust turbocharger and cannot be replaced individually.
5. Combination valve
- For Secondary Air Injection (AIR) system
6. Fuel pressure regulator
7. To cylinder head cover
- Crankcase breather valve
8. To brake booster
9. Suction jet pump
10. Vacuum reservoir
- Two separate chambers
11. To diagnostic pump
12. Check valve
- Bypass to vacuum booster
13. Check valve
- For engine vacuum control
14. Crankcase ventilation
15. Secondary Air Injection (AIR) Solenoid Valve -N112-
16. Check valve
- For EVAP canister system
17. Check valve
- For diagnostic pump
18. Charge Air Pressure Sensor -G31-*
19. Charge air cooler
20. Throttle valve control module
21. Intake manifold
22. Recirculating valve for turbocharger -N249-
23. Vacuum diaphragm
- For charge pressure regulator valve
- Part of turbocharger, cannot be replaced
24. Wastegate Bypass Regulator Valve -N75-*
- Valve is activated (pulsed) by the Engine Control Module (ECM)
- Closed when no voltage present, limits charge pressure
- Check activation
25. Deceleration shut-off valve
26. Pressure regulator valve
- For crankcase ventilation
27. Secondary Air Injection (AIR) Pump Motor -V101-*
- Checking function
28. Evaporative Emission (EVAP) Canister Purge Regulator Valve -N80-*
