MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-343
STEP 19. Check for leaks in the evaporator line from hose
J to hose K.
(1) The leakage test with a hand vacuum pump on each hose
from hose J to hose K.
Q: Can the leaks be pin pointed?
YES : Replace that hose, and go to Step 32.
NO : Go to Step 32.
STEP 20. Check for clogging in the evaporator line from
hose G to hose I.
(1) Unplug hose G.
(2) On the EVAP pressure pump, set the pressure/hold valve to
OPEN, and set the vent valve to CLOSED. Turn the pump
timer to ON. You can reset the timer as required. (These
settings are listed under "Leak Test" in the pump
instructions.)
(3) Air should pass through hose G.
Q: Does air pass through hose G?
YES : Go to Step 24.
NO : Go to Step 21.

STEP 21. Check for clogging in the evaporator line from
hose I to hose P.
(1) Disconnect hose I from the evaporative emission canister
side, and unplug the hose I.
(2) On the EVAP pressure pump, set the pressure/hold valve to
OPEN, and set the vent valve to CLOSED. Turn the pump
timer to ON. You can reset the timer as required. (These
settings are listed under "Leak Test" in the pump
instructions.)
(3) Air should pass through hose I.
Q: Does air pass through hose I?
YES : Go to Step 22.
NO : Go to Step 27.
STEP 22. Check for clogging in the evaporator line from
hose H and G.
(1) Remove the fuel tank. (Refer to GROUP 13C, Fuel Tank
(2) The clogging test with a hand vacuum pump on each hose
from hose H and hose G.
Q: Are there any clogs?
YES : Replace that hose, and perform the OBD-II drive
cycle
NO : Go to Step 23.

STEP 23. Check for clogging in the evaporative emission
canister.
(1) Connect a hand vacuum pump to the vent nipple of the
evaporative emission canister.
(2) Plug the other two nipples or loop a hose between the other
nipples.
(3) Apply a vacuum, when each nipple is unplugged, the
vacuum should fluctuate.
Q: Does the vacuum pump gauge reading fluctuate?
YES : Reinstall the fuel tank. Then perform the OBD-II drive
cycle
NO : Replace the evaporative emission canister, reinstall
the fuel tank. Then perform the OBD-II drive cycle
.
STEP 24. Check for clogging in the evaporator line hose F.
(1) Disconnect hose F at the intake manifold side, and then
connect a hand vacuum pump to hose F at the floor pipe
side.
(2) Apply vacuum.
NOTE: The vacuum should be 40 kPa (5.8 psi) or less.
(3) Use scan tool MB991502 to activate the evaporative
emission purge solenoid valve. The vacuum should leak.
Q: Is the vacuum maintained inside the evaporator line?
YES : Go to Step 25.
NO : Go to Step 26.
STEP 25. Check for clogging in the evaporator line hose C
to hose E.
(1) The clogging test with a hand vacuum pump on each hose
from hose C to hose E.
Q: Are there any clogs?
YES : Replace that hose, and perform the purge flow check.
(Refer to GROUP 17, Purge Control System Check
NO : Perform the OBD-II drive cycle

STEP 26. Check for clogging in the evaporator line from
hose F.
(1) Remove the fuel tank. (Refer to GROUP 13C, Fuel Tank
(2) The clogging test with a hand vacuum pump on each hose
from hose F.
Q: Are there any clogs?
YES : Replace that hose, and perform the OBD-II drive
cycle

STEP 27. Check for clogging in the evaporator line hose I,
L, M, N and hose O.
(1) Remove the filler neck assembly. (Refer to GROUP 13C,
Fuel Tank
.)
(2) The clogging test with a hand vacuum pump on each hose
from hose I, L, M, N and hose O.
Q: Are there any clogs?
YES : Replace that hose, reinstall the filler neck assembly
and filler neck protector, and perform the OBD-II drive
cycle
NO : Go to Step 28.
