Check Fuel Level Sensor

DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK COMMUNICATION ERROR DISPLAY. 
  1. Turn the ignition switch to ON.
  2. Check that the error code is displayed in ODO/trip meter.
 Is the error code "Er xx" displayed in ODO/trip meter? Check the communication circuit. < Refer to COMMUNICATION ERROR DISPLAY , INSPECTION, COMBINATION METER SYSTEM. > Go to step 2.
2 CHECK FUEL LEVEL SENSOR. 
  1. Remove the fuel level sensor. < Refer to REMOVAL , Fuel Level Sensor. >
  2. Measure the resistance between fuel level sensor terminals when the float is in FULL or EMPTY position.

Terminals 

No. 1 - No. 4: 

 Is the resistance 1.0 to 3.0 Ω (FULL) and 31 to 33 Ω (EMPTY)? Go to step 3. Replace the fuel level sensor.
3 CHECK FUEL SUB LEVEL SENSOR. 
  1. Remove the fuel sub level sensor. < Refer to REMOVAL , Fuel Sub Level Sensor. >
  2. Measure the resistance between fuel sub level sensor terminals when the float is in FULL or EMPTY position.

Terminals 

No. 1 - No. 2: 

 Is the resistance 1.0 to 3.0 Ω (FULL) and 61 to 63 Ω (EMPTY)? Go to step 4. Replace the fuel sub level sensor.
4 CHECK HARNESS BETWEEN FUEL SUB-LEVEL SENSOR AND BODY INTEGRATED MODULE. 
  1. Disconnect the connector from body integrated unit.
  2. Measure the resistance between fuel sub level sensor harness connector terminal and body integrated unit harness connector terminal.

Connector & terminal 

(R59) No. 1 - (B281) No. 19: 

 Is the resistance less than 10 Ω? Go to step 5. Repair the wiring harness.
5 CHECK HARNESS BETWEEN FUEL LEVEL SENSOR AND FUEL SUB LEVEL SENSOR. 
Measure the resistance between fuel level sensor harness connector terminal and fuel sub level sensor harness connector terminal.

Connector & terminal 

(R58) No. 1 - (R59) No. 2: 

 Is the resistance less than 10 Ω? Go to step 6. Repair the wiring harness.
6 CHECK FUEL LEVEL SENSOR GROUND CIRCUIT. 
Measure the resistance between fuel level sensor harness connector terminal and chassis ground.

Connector & terminal 

(R58) No. 4 - Chassis ground: 

 Is the resistance less than 10 Ω? Replace the meter case assembly. Repair the wiring harness.
