MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI)
13A-409
STEP 6. Measure the sensor supply voltage at fuel tank
temperature sensor harness side connector E-30.
(1) Disconnect the connector E-30 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 1 and ground.
• Voltage should be between 4.5 and 4.9 volts
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.5 and 4.9 volts?
YES : Go to Step 8.
NO : Go to Step 7.
STEP 7. Check connector C-90 at PCM for damage.
Q: Is the connector in good condition?
YES : Replace the PCM. Then go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.

STEP 8. Check for continuity at fuel tank temperature
sensor harness side connector E-30.
(1) Disconnect the connector E-30 and measure at the harness
side.
(2) Check for the continuity between terminal No. 3 and
ground.
• Should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 9.
NO : Check connector E-44 at intermediate connector for
damage, and repair or replace as required. Refer to
GROUP 00E, Harness Connector Inspection
. If intermediate connector is in good
condition, repair harness wire between fuel tank
temperature sensor connector E-30 (terminal No. 3)
and ground because of open circuit or harness
damage. Then go to Step 12.
STEP 9. Check the fuel tank temperature sensor.
(1) Disconnect the fuel tank temperature sensor connector
E-30.
(2) Measure the resistance between terminal No. 1 and No. 3
of the fuel tank temperature sensor.
Standard value:
0.5
− 12.0 kΩ
Q: Is the resistance between 0.5 and 12.0 k
Ω?
YES : Go to Step 10.
NO : Replace the fuel tank temperature sensor. Then go to
Step 12.

STEP 10. Check connector C-90 at PCM 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
. Then go to Step 12.
STEP 11. Check for harness damage between fuel tank
temperature sensor connector E-30 (terminal No. 1) and
PCM connector C-90 (terminal No. 51).
NOTE: Check harness after checking intermediate connector
C-85 and E-44. If intermediate connectors are damaged, repair
or replace them. Refer to GROUP 00E, Harness Connector
Inspection
. Then go to Step 12.
Q: Is the harness wire in good condition?
YES : Replace the PCM. Then go to Step 12.
NO : Repair it. 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
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0181 set?
YES : Repeat the troubleshooting.
NO : The procedure is complete.
