STEP 5. 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) Disconnect the fuel tank temperature sensor connector 

D-17.

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

(4) Measure the voltage between terminal No. 77 <M/T> or No. 

51 <A/T> 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 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-28 and C-90 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 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 11.

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

Connector Inspection 

P.00E-2

. Then go to Step 11.
