MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-232

STEP 14. Check the heated oxygen sensor (front).
(1) Disconnect the heated oxygen sensor (front) connector 

B-17 and connect test harness special tool, MD998464, to 
the connector on the heated oxygen sensor (front) side.

(2) Warm-up the engine until engine coolant 80

°C (176°F) or 

higher.

CAUTION

Be very careful when connecting the jumper wires; incor-
rect connection can damage the heated oxygen sensor 
(front).

(3) Use the jumper wires to connect terminal No. 1 (red clip) to 

the positive battery terminal and terminal No. 3 (blue clip) to 
the negative battery terminal.

(4) Connect a digital volt meter between terminal No. 2 (black 

clip) and terminal No. 4 (white clip).

(5) While repeatedly revving the engine, measure the heated 

oxygen sensor (front) output voltage.

Standard value: 0.6 

 1.0 volt

Q: Is the voltage between 0.6 and 1.0 volt?

YES : Replace the ECM or PCM. Then go to Step 15.
NO :  Replace the heated oxygen sensor (front). Then go to 

Step 15.

STEP 15. 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 P0130 set?

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