STEP 3. Check the fuel tank temperature sensor.
(1) Disconnect the fuel tank temperature sensor connector G-

03

(2) Measure the resistance between terminal No. 2 and No. 3

of the fuel tank temperature sensor.

Standard value:

0.5

− 12.0 kiloohms

Q: Is the resistance between 0.5 and 12.0 kiloohms?

YES : Go to Step 4.
NO : Replace the fuel tank temperature sensor. Then go to

Step 11.

STEP 4. Check the sensor supply voltage at fuel tank
temperature sensor harness side connector G-03.
(1) Disconnect the connector G-03 and measure at the harness

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 3 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 5.

STEP 5. Check the sensor supply voltage at PCM
connector D-134 by backprobing.
(1) Do not disconnect the PCM connector D-134.
(2) Disconnect the fuel tank temperature sensor connector G-

03.

(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal No. 81 and ground

by backprobing.

• Voltage should be between 4.5 and 4.9 volts.

(5) 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 6.
NO : Go to Step 7.

STEP 6. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Check connector D-111, E-113 and F-07 at

intermediate connector for damage, and repair or
replace as required. Refer to GROUP 00E, Harness
Connector Inspection

P.00E-2

. If intermediate

connector are in good condition, repair harness wire
between fuel tank temperature sensor connector G-
03 and PCM connector D-134 because of open
circuit. Then go to Step 11.

NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 11.

STEP 7. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Replace the PCM. Then go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 11.

STEP 8. Check the continuity at fuel tank temperature
sensor harness side connector G-03.
(1) Disconnect the connector G-03 and measure at the harness

side.

(2) Check for the continuity between terminal No. 2 and

ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Go to Step 9.
NO : Check connector F-07 at intermediate connector for

damage, and repair or replace as required. Refer to
GROUP 00E, Harness Connector Inspection

P.00E-

2

. If intermediate connector is in good condition,

repair harness wire between fuel tank temperature
sensor connector G-03 (terminal No. 2) and ground
because of open circuit or harness damage. Then go
to Step 11.
