With Automatic Transmission

VACUUM SYSTEM DIAGRAM

Automatic transmission vehicles with EVAP system and EGR

NOTE:
On automatic transmission vehicles with EVAP and EGR there are two system variations.

Vacuum Hose Diagram:

Variation 1
1 - Vacuum brake booster
2 - Vent line from EGR solenoid valve
3 - Exhaust Gas Recirculation (EGR) valve
4 - Check valve
5 - Vacuum booster
6 - Vacuum unit for intake manifold change-over
7 - Intake manifold
8 - Ignition coils
9 - Vacuum reservoir for intake manifold change-over valve
10 - Fuel pressure regulator
11 - Restrictor 1
12 - EGR vacuum regulator solenoid valve
13 - Restrictor 2
