MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-63

STEP 14. Check for open circuit and harness damage
between intake air temperature sensor connector B-14
terminal 5 and ECM connector C-58 terminal 49 <M/T> or
PCM connector C-55 terminal 57 <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 19.
NO : Repair it. Then go to Step 19.

STEP 15. Check the intake air temperature sensor.
(1) Disconnect the intake air temperature sensor connector B-

14

(2) Measure the resistance between intake air temperature

sensor side connector terminal 5 and 6.

(3) Measure resistance while heating the sensor using a hair

drier.

Q: Is the resistance at the standard value?

YES : Go to Step 16.
NO : Replace the volume air flow sensor. Then go to Step

19.

STEP 16. Check connector C-58 at ECM <M/T> or
connector C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 17.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection (

P.00E-2

). Then go to Step 19.
