MULTIPORT FUEL INJECTION (MFI) <3.0L>
13B-483
(3) Measure the voltage between terminal No. 96 <M/T> or
terminal No. 51 <A/T> 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 C-62 at ECM <M/T> or connector
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Check connector C-28 and C-90 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 D-17 (terminal No. 3) and ECM
connector C-62 (terminal No. 96) <M/T> or PCM
connector C-55 (terminal No. 51) <A/T> 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.
