MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-76

DIAGNOSIS

Required Special Tools

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

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

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) Set scan tool MB991958, read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the diagnostic trouble code other than P0014 set?

YES : Refer to, Diagnostic Trouble Code Chart 

P.13A-49

.

NO :  Go to Step 2.

STEP 2. Check exhaust engine oil control valve itself.

• Check exhaust engine oil control valve itself (Refer to 

Engine Oil Control Valve Check 

P.13A-878

).

Q: Is the check result normal?

YES : Go to Step 3. 
NO :  Replace exhaust engine oil control valve. Then go to 

Step 6.

STEP 3. Check oil passage of exhaust variable valve timing 
control system for being clogged.
Q: Is the check result normal? 

YES : Go to Step 4.
NO :  Repair it. Then go to Step 6.

STEP 4. Check exhaust variable valve timing sprocket 
operation mechanism for being stuck.
Q: Is the check result normal?

YES : Go to Step 5.
NO :  Repair it. Then go to Step 6.

13A-77

STEP 5. Check the trouble symptoms.
(1) Carry out test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle − Pattern 20 

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0014 set?

YES : Replace the ECM. When the ECM is replaced, 

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Code Registration Judgment Table <Vehicles 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM> 

P.42C-10

. Then go to Step 6.

NO :  It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunctions 

P.00-15

.

STEP 6. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle − Pattern 20 

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0014 set?

YES : Retry the troubleshooting.
NO :  The inspection is complete.

DTC P0016: Crankshaft/camshaft (intake) Position Sensor Phase Problem

.

TECHNICAL DESCRIPTION

tem for malfunction.

.

DESCRIPTIONS OF MONITOR METHODS

than the specified value.

.

MONITOR EXECUTION

Continuous
