STEP 6. Measure the sensor supply voltage at ECM 
connector C-60 <M/T> or PCM connector C-54 <A/T> by 
backprobing.
(1) Do not disconnect the ECM connector C-60 <M/T> or PCM 

connector C-54 <A/T>.

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

(3) Measure the voltage between terminal No. 77 <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-60 at ECM <M/T> or connector 
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES :  Check connector C-90 and C-28 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 level 
sensor connector D-17 (terminal No. 3) and ECM 
connector C-60 (terminal No. 77) <M/T> or PCM 
connector C-54 (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 

P.00E-2

. Then go to Step 12.
