MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-513
STEP 4. Measure the 5-volt reference signal at ECM
connector B-11 by using check harness special tool
MB992110.
(1) Disconnect all ECM connectors. Connect the power plant
ECU check harness special tool MB992110 between the
separated connectors.
(2) Turn the ignition switch to the "ON" position.
(3) Remove the fuel cap.
(4) Measure the voltage between terminal 114 and ground.
• The voltage should measure between 4.9 and 5.1 volts.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.9 and 5.1 volts?
YES : Check harness connector C-129 at intermediate
connector for damage, and repair or replace as
required. Refer to GROUP 00E, Harness connector
Inspection
. If intermediate connector C-129
is in good condition, repair it because of harness
damage fuel tank differential pressure sensor
connector D-19 (terminal No. 3) and ECM connector
B-11 (terminal No. 114). Then go to Step 7 .
NO : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, ID Code
Registration Judgment Table <Vehicles with KOS>
or GROUP 42C, ID Code Registration
Judgment Table <Vehicles with WCM>
Then go to Step 7 .

STEP 5. Check the harness wire between ECM connector
B-11 and fuel tank differential pressure sensor connector
D-19 for damage.
(1) Disconnect the connector B-11 and D-19 measure at the
harness side.
(2) Measure the resistance between connector B-11 and
connector D-19.
a. Connector B-11 (terminal No. 112) and connector D-19
(terminal No. 1).
b. Connector B-11 (terminal No. 113) and connector D-19
(terminal No. 2).
• Should be less than 2 ohms.
Q: Is the measured resistance less than 2 ohms?
YES : Go to Step 6 .
NO : Repair the damaged harness wires. Then go to Step 7
STEP 6. Replace the fuel tank differential pressure sensor.
(1) Replace the fuel tank differential pressure sensor.
(2) Carry out test drive with the drive cycle pattern. Refer to
Diagnostic Function. OBD-II Drive Cycle. Pattern 16
(3) Check the diagnostic trouble code (DTC).
Q: Is DTC P0451 set?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, ID Code
Registration Judgment Table <Vehicles with KOS>
or GROUP 42C, ID Code Registration
Judgment Table <Vehicles with WCM>
Then go to Step 7 .
NO : The inspection is complete.
STEP 7. Perform the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function
− OBD-II Drive Cycle − Pattern 16
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0451 set?
YES : Repeat the troubleshooting.
NO : The procedure is complete.
