MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-327

STEP 4. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection (

P.00E-2

). Then go to Step 12.

STEP 5. Check for open circuit and short circuit to ground
between manifold differential pressure sensor connector
B-04 terminal 3 and ECM connector C-60 terminal 81 <M/T>
or PCM connector C-54 terminal 46 <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 6. Check the continuity at manifold differential
pressure sensor harness side connector B-04.
(1) Disconnect the connector B-04 and measure at the harness

side.

(2) Measure the continuity between terminal 2 and ground.

•

Should be less than 2 ohm.

Q: Is the continuity normal?

YES : Go to Step 9.
NO : Go to Step 7.

STEP 7. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection (

P.00E-2

). Then go to Step 12.

STEP 8. Check for open circuit and harness damage
between manifold differential pressure sensor connector
B-04 terminal 2 and ECM connector C-60 terminal 92 <M/T>
or PCM connector C-54 terminal 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 C-60 at ECM <M/T> or connector
C-54, C-57 at PCM <A/T> 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.
