TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-801

STEP 15. Check the purge control system.
Refer to GROUP 17, Emission Control 

− Evaporative Emission 

Control System 

− Purge Control System Check (Purge Flow 

Check) 

P.17-77

.

Q: Is the purge control system normal?

YES : Go to Step 16.
NO :  Repair it. Then confirm that the malfunction symptom 

is eliminated.

STEP 16. Check the following items.
(1) Check the following items.

a. Check the injectors for fuel leakage.
b. Check if the injectors are clogged.

Q: Are there any abnormalities?

YES : Replace it. Then confirm that the malfunction 

symptom is eliminated. Then confirm that the 
malfunction symptom is eliminated.

NO :  Replace the catalytic converter. Then confirm that the 

malfunction symptom is eliminated.

INSPECTION PROCEDURE 19: Purge Flow Test of the Evaporative Emission Canister Failure.

.

COMMENT

• The test fails when the purge line or purge port is 

clogged or if the evaporative emission purge 
solenoid fails.

.

TROUBLESHOOTING HINTS (The most 
likely causes for this case:)

• Purge line or purge port is clogged.

• Malfunction of the evaporative emission purge 

solenoid.

• Evaporative emission canister is clogged.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-802

STEP 1. Using scan tool MB991958, read the diagnostic 
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is any DTC set?

YES : Refer to Diagnostic Trouble Code Chart 

P.13B-50

.

NO :  Refer to GROUP 17, Emission Control 

− Evaporative 

Emission Control System 

− Purge Control System 

Check (Purge Flow Check) 

P.17-77

.

INSPECTION PROCEDURE 20: Pressure Test of the Evaporative System Failure

.

COMMENT

• The test fails if there is a leak from the fuel tank or 

vapor line.

.

TROUBLESHOOTING HINTS (The most 
likely causes for this case:)

• Loose fuel tank filler tube cap.

• Broken seal in fuel tank, vapor line evaporative 

emission canister.

DIAGNOSIS

STEP 1. Check the evaporative emission purge solenoid.
Refer to GROUP 17, Emission Control 

− Evaporative Emission 

Control System 

− Evaporative Emission Purge Solenoid Check 

P.17-78

.

Q: Is the evaporative emission purge solenoid normal?

YES : Go to Step 2.
NO :  Repair or replace it. Then confirm that the malfunction 

symptom is eliminated.

STEP 2. Check the evaporative emission ventilation 
solenoid.
Refer to GROUP 17, Emission Control 

− Evaporative Emission 

Control System 

− Evaporative Emission Ventilation Solenoid 

Check 

P.17-80

.

Q: Is the evaporative emission ventilation solenoid 

normal?
YES : Check the following items, and repair or replace the 

defective items.

a. Check for leaks from the vapor line or 

evaporative emission canister.

b. Check for leaks from the fuel tank.

Then confirm that the malfunction symptom is 

eliminated.

NO :  Repair or replace it. Then confirm that the malfunction 

symptom is eliminated.
