MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-291

STEP 8. Check harness connector B-11 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 9.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 10.

STEP 9. Check for harness damage between fuel tank 
temperature sensor connector D-20 (terminal No. 3) and 
ECM connector B-11 (terminal No. 115).
NOTE: Check harness after checking intermediate connector 
C-129. If the intermediate connector is damaged, repair or 
replace it. Refer to GROUP 00E, Harness Connector Inspec-
tion 

P.00E-2

. Then go to Step 10.

Q: Is the harness wire in good condition?

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 10.

NO :  Repair it. Then go to Step 10.

STEP 10. 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 23 

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0183 set?

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

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-293

.

CIRCUIT OPERATION

• The injector power is supplied from the injector 

relay (terminal No. 3).

• The ECM controls the injector by turning the 

power transistor in the ECM "ON" and "OFF".

.

TECHNICAL DESCRIPTION

• The amount of fuel injected by the injector is con-

trolled by the amount of continuity time the coil is 
grounded by the ECM.

.

DESCRIPTIONS OF MONITOR METHODS

The ECM detects open circuit and short malfunction.

.
