MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-279

STEP 6. Check for harness damage between fuel tank
temperature sensor connector D-20 (terminal No. 3) and
ECM connector B-11 (terminal No. 115).
NOTE: Check harness after checking intermediate connector
C-129. If intermediate connector is damaged, repair or replace
it. Refer to GROUP 00E, Harness Connector Inspection

P.00E-2

. Then go to Step 7.

Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID

Codes Registration Judgment Table <Vehicles with
WCM>

P.42C-10

. Then go to Step 7.

NO : Repair it. Then go to Step 7.

STEP 7. 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 − Pattern 14

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0181 set?

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

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

.

CIRCUIT OPERATION

• 5-volt voltage is applied to the fuel tank tempera-

ture sensor output terminal (terminal No. 3) from
the ECM (terminal No. 115) via the resistor in the
ECM.

• The fuel tank temperature sensor output voltage

increases when the resistance increases and
decreases when the resistance decreases. The
ground terminal (terminal No. 1) is grounded to
the vehicle body.

.

TECHNICAL DESCRIPTION

• The fuel tank temperature sensor converts the

fuel tank temperature to a voltage.

• The ECM detects the fuel tank temperature with

this output voltage.

.

DESCRIPTIONS OF MONITOR METHODS

Fuel tank temperature sensor output voltage is out of

specified range.

.

MONITOR EXECUTION

Continuous

TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)

• Fuel tank temperature sensor failed.

• Shorted fuel tank temperature sensor circuit, or

connector damage.

• ECM failed.
