TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-69

STEP 7. Check connector C-40 at PCM for damage.
Q: Is the connector in good condition?

YES : Replace the PCM. Then go to Step 14.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection(

P.00E-2

). Then go to Step 14.

STEP 8. Check the continuity at engine coolant
temperature sensor harness side connector B-13.
(1) Disconnect the connector B-13 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 11.
NO : Go to Step 9.

STEP 9. Check connector C-40 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection(

P.00E-2

). Then go to Step 14.

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

connector B-13

(2) Remove the engine coolant temperature sensor.
(3) With the temperature sensing portion of engine coolant

temperature sensor immersed in hot water, check
resistance.
