MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-141

STEP 11. Check the engine coolant temperature sensor.
(1) Disconnect the engine coolant temperature sensor 

connector B-11.

(2) Remove the engine coolant temperature sensor.

(3) With the temperature sensing portion of engine coolant 

temperature sensor immersed in hot water, check 
resistance.

Standard value:

14 

− 17 kΩ [at −20°C (−4°F)]

5.1 

− 6.5 kΩ [at 0°C (32°F)]

2.1 

− 2.7 kΩ [at 20°C (68°F)]

0.9 

− 1.3 kΩ [at 40°C (104°F)]

0.48 

− 0.68 kΩ [at 60°C (140°F)]

0.26 

− 0.36 kΩ [at 80°C (176°F)]

(4) Apply 3M

 AAD part number 8731 or equivalent on the 

screw section of the engine coolant temperature sensor.

(5) Install the engine coolant temperature sensor, and tighten 

to the specified torque.

Tightening torque: 29 

± 10 N⋅m (22 ± 7 ft-lb)

Q: Is the resistance at the standard value?

YES : Go to Step 12.
NO :  Replace the engine coolant temperature sensor. Then 

go to Step 14.

STEP 12. Check connector C-60 at ECM <M/T> or 
connector C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 13.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 14.

STEP 13. Check for harness damage between engine 
coolant temperature sensor connector B-11 (terminal No. 
1) and ECM connector C-60 (terminal No. 83) <M/T> or PCM 
connector C-54 (terminal No. 44) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO :  Repair it. Then go to Step 14.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-144

STEP 14. 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
