MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-149

STEP 3. Check for the continuity between the mass airflow 
sensor connector A-07 and the ECM connector B-11.
(1) Disconnect the mass airflow sensor connector A-07 and the 

ECM connector B-11.

(2) Check for the continuity between the mass airflow sensor 

connector A-07 (terminal No. 4) and the ECM connector 
B-11 (terminal No. 88).

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 4.
NO :  Repair it. Then go to Step 5.

STEP 4. Replace the mass airflow sensor.
(1) Replace the mass airflow sensor.
(2) Carry out a test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle − Pattern 22 

P.13B-11

.

(3) Check the diagnostic trouble code (DTC).
Q: Is DTC P0102 set?

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

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Codes 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 5.

NO :  The inspection is complete.

STEP 5. 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 22 

P.13B-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0103 set?

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

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-151

CIRCUIT OPERATION

• A 5-volt voltage is supplied to the manifold abso-

lute pressure sensor power terminal (terminal No. 
3) from the ECM (terminal No. 44). The ground 
terminal (terminal No. 2) is grounded with ECM 
(terminal No. 46).

• A voltage that is proportional to the intake mani-

fold pressure is sent to the ECM (terminal No. 45) 
from the manifold absolute pressure sensor out-
put terminal (terminal No. 1).

.

TECHNICAL DESCRIPTION

• The manifold absolute pressure sensor outputs a 

voltage which corresponds to the intake manifold 
pressure.

• The ECM checks whether this voltage is within a 

specified range.

.

DESCRIPTIONS OF MONITOR METHODS

Compare load value with manifold absolute pressure 

sensor output voltage.

.

MONITOR EXECUTION

Continuous
