MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-65

STEP 8. Check for harness damage between manifold 
absolute pressure sensor connector B-04 (terminal No. 2) 
and ECM connector C-60 (terminal No. 92) <M/T> or PCM 
connector C-54 (terminal No. 57) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 12.
NO :  Repair it. Then go to Step 12.

STEP 9. Check connector B-04 at manifold absolute 
pressure sensor 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 12.

STEP 10. Check connector C-60 at ECM <M/T> or 
connector C-57 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 11.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 12.

STEP 12. 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.13A-5

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0106 set?

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