MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-79
STEP 5. Check for open circuit between engine coolant
temperature sensor connector B-11 terminal 1 and ECM
connector C-60 terminal 83 <M/T> or PCM connector C-54
terminal 44 <A/T>.
Q: Is the harness wire in good condition?
YES : Replace the ECM or PCM. Then go to Step 11.
NO : Repair it. Then go to Step 11.
STEP 6. Check the continuity at engine coolant
temperature sensor harness side connector B-11.
(1) Disconnect the connector B-11 and measure at the harness
side.
(2) Check for the continuity between terminal 2 and ground.
•
Should be less than 2 ohm.
Q: Is the continuity normal?
YES : Go to Step 9.
NO : Go to Step 7.

STEP 9. 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.

Q: Is the resistance at the standard value?
YES : Go to Step 10.
NO : Replace the engine coolant temperature sensor. Then
go to Step 11.
STEP 10. 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 : Replace the ECM or PCM. Then go to Step 11.
