DIAGNOSTIC TROUBLE CODE PROCEDURES
13Ac-301
STEP 6. Measure the sensor supply voltage at PCM
connector D-134 by backprobing.
(1) Do not disconnect the PCM connector D-134.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 81 and ground
by backprobing.
• When fuel tank temperature is 0°C (32°F), voltage
should be 2.7 and 3.1 volts.
• When fuel tank temperature is 20°C (68°F), voltage
should be 2.1 and 2.5 volts.
• When fuel tank temperature is 40°C (104°F), voltage
should be 1.6 and 2.0 volts.
• When fuel tank temperature is 80°C (176°F), voltage
should be 0.8 and 1.2 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 7.
NO : Go to Step 8.
STEP 7. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?
YES : Check connector D-111 and F-07 at intermediate
connector for damage, and repair or replace as
required. Refer to GROUP 00E, Harness Connector
Inspection
. If intermediate connector are in
good condition, repair harness wire between fuel level
sensor connector G-03 (terminal No. 3) and PCM
connector D-134 (terminal No. 81) because of open
circuit. Then go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.
