EGR FUNCTION TESTING

Colt Wagon 1.8L, Montero (A/T), Raider (A/T), Sigma,

Van/Wagon & All Other Federal Models (Ported EGR Valve)

1) Disconnect Green-striped hose from throttle body and

connect a vacuum pump to hose end. Plug nipple where hose was

connected to throttle body. With engine temperature 122 F (50 C) or

less, and engine idling, apply vacuum to hose. If idle does not change

and vacuum leaks down, system is functioning properly.

2) With engine temperature 176-205 F (80-95 C) and engine

idling, apply 2 in. Hg to hose. If idle does not change, and vacuum

holds, system is functioning properly.

3) Apply 7.7 in. Hg. If vacuum holds and idle becomes

unstable or engine stalls, EGR system is functioning properly.

Montero (M/T), Raider (M/T) & All Other California

Models (Ported EGR Valve)

1) Connect a vacuum tee into Green-striped hose from EGR

valve and connect a vacuum pump to vacuum tee. With engine temperature

68 F (20 C) or less and engine idling, snap throttle opened and

closed. If no change in vacuum reading on vacuum pump gauge is

detected, system is functioning properly.

2) With engine temperature 158 F (70 C) or higher and engine

idling, snap throttle open to race engine. If vacuum is now indicated

on vacuum pump gauge, system is functioning properly.

3) Using a vacuum pump, apply specified vacuum to open EGR

valve. See appropriate EGR VALVE SPECIFICATIONS table. If idle becomes

unstable or engine stalls, EGR system is functioning properly.
