MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-115

STEP 10. Check for open circuit and harness damage
between right bank heated oxygen sensor (front)
connector B-27 terminal 2 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 15.
NO : Repair it. Then go to Step 15.

STEP 11. Check connector C-62 at ECM <M/T> or
connector C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection (

P.00E-2

). Then go to Step 15.

STEP 13. Check for short circuit to ground and harness
damage between right bank heated oxygen sensor (front)
connector B-27 terminal 4 and ECM connector C-62
terminal 72 <M/T> or PCM connector C-59 terminal 72 <A/
T>.
Q: Is the harness wire in good condition?

YES : Go to Step 14.
NO : Repair it. Then go to Step 15.

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

connector B-27 and connect test harness special tool,
MD998464, to the connector on the right bank 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;
incorrect connection can damage the right bank heated
oxygen sensor (front).
(3) Use the jumper wires to connect terminal 1 (red clip) to the

positive battery terminal and terminal 3 (blue clip) to the
negative battery terminal.

(4) Connect a digital volt meter between terminal 2 (black clip)

and terminal 4 (white clip).

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

bank heated oxygen sensor (front) output voltage.

Standard value: 0.6

−

1.0 V

Q: Is the voltage at the standard value?

YES : Replace the ECM or PCM. Then go to Step 15.
NO : Replace the right bank 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,

Procedure 4

−

Heated oxygen Sensor Monitor and

Procedure 6

−

Other Monitor (

P.13B-4

).

(2) Check the diagnostic trouble code (DTC).

Q: Is the DTC P0130 is output?

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