MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-457

(4) Measure the voltage between terminal No. 41 and ground.

• Voltage should be between 4.5 and 4.9 volts.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.5 and 4.9 volts?

YES : Go to Step 6.
NO :  Go to Step 7.

STEP 6. Check harness connector B-20 at PCM for 
damage.

Q: Is the harness connector in good condition?

YES : Check harness connector C-25 at intermediate 

connector for damage, and repair or replace as 
required. Refer to GROUP 00E, Harness Connector 
Inspection 

P.00E-2

. If the intermediate connector is in 

good condition, repair the harness wire between fuel 
tank temperature sensor connector D-18 and PCM 
connector B-20 because of open circuit. Then go to 
Step 11.

NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 7. Check harness connector B-20 at PCM for 
damage.

Q: Is the harness connector in good condition?

YES : Replace the PCM. Then go to Step 11.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 8. Check the continuity at fuel tank temperature 
sensor harness side connector D-18.

(1) Disconnect the connector D-18 and measure at the harness 

side.

(2) Check for the continuity between terminal No. 1 and 

ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 9.
NO :  Repair harness wire between fuel tank temperature 

sensor connector D-18 (terminal No. 1) and ground 
because of open circuit or harness damage. Then go 
to Step 11.

STEP 10. Check for open circuit and harness damage 
between fuel tank temperature sensor connector D-18 and 
PCM connector B-20.

NOTE: Check harness after checking intermediate connector 
C-25. 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 11.

Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 11.
NO :  Repair it. Then go to Step 11.

STEP 11. 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 − Procedure 6 − 

Other Monitor 

P.13A-5

.

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