MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-115

STEP 3. 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 No. 5 and No. 6.

• There should be continuity. (0.30 − 20 kΩ)

Q: Is the measured resistance between 0.30 and 20 k

Ω?

YES : Go to Step 4.
NO :  Replace the volume airflow sensor. Then go to Step 6.

STEP 4. Check for short circuit to ground between intake 
air temperature sensor connector B-14 and ECM 
connector C-58 <M/T> or PCM connector C-55 <A/T>.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair it. Then go to Step 6.

STEP 5. 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 : Replace the ECM or PCM. Then go to Step 6.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 6.

STEP 6. 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.13B-7

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0112 set?

YES : Retry the troubleshooting.
NO :  The inspection is complete.
