Check Fuel Level Sensor

FUEL LEVEL SENSOR

Step Check Yes No
1 CHECK ENGINE MODEL.  Is the engine with TURBO? Go to step 7.  Go to step 2. 
2 CHECK FUEL LEVEL SENSOR. 
  1. Remove the fuel level sensor. < Ref. to REMOVAL , Fuel Level Sensor . >
  2. Measure the resistance between the fuel level sensor terminals when setting the float to FULL and EMPTY position.

Terminals 
No. 3 - No. 6 		 Is the measured value 0.5 to 2.5 ohm at FULL or 52.5 to 54.5 ohm at EMPTY? Go to step 3.  Replace the fuel level sensor.
3 CHECK FUEL SUB LEVEL SENSOR. 
  1. Remove the fuel sub level sensor. < Ref. to REMOVAL , Fuel Sub Level Sensor . >
  2. Measure the resistance between the fuel sub level sensor terminals when setting the float to FULL and EMPTY position.

Terminals. 
No. 1 - No. 2 		 Is the measured value 0.5 to 2.5 ohm at FULL or 39.5 to 41.5 ohm. at EMPTY? Go to step 4.  Replace the fuel sub level sensor.
4 CHECK HARNESS BETWEEN FUEL SUB LEVEL SENSOR AND COMBINATION METER. 
  1. Disconnect the connector from the combination meter.
  2. Measure the resistance between the fuel sub level sensor harness connector terminal and combination meter harness connector terminal.

Connector & terminal 
(R59) No. 1 - (i10) No. 3: 		 Is the measured value less than 10 ohm? Go to step 5.  Repair wiring harness.
5 CHECK HARNESS BETWEEN FUEL LEVEL SENSOR AND FUEL SUB LEVEL SENSOR. 
Measure the resistance between the fuel level sensor harness connector terminal and fuel sub level sensor harness connector terminal.
Connector & terminal 
(R58) No. 6 - (R59) No. 2: 		 Is the measured value less than 10 ohm? Go to step 6.  Repair wiring harness.
6 CHECK FUEL LEVEL SENSOR GROUND CIRCUIT. 
Measure the resistance between the fuel level sensor harness connector terminal and chassis ground.
Connector & terminal 
(R58) No. 3 - Chassis ground: 		 Is the measured value less than 10 ohm? Check the fuel gauge. < Ref. to , REMOVAL , Fuel Gauge. > Repair wiring harness.
7 CHECK FUEL LEVEL SENSOR. 
  1. Remove the fuel level sensor. < Ref. to REMOVAL , Fuel Level Sensor. >
  2. Measure the resistance between fuel level sensor terminals when setting the float to FULL and EMPTY position.

Terminals 
No. 2 - No. 3: 		 Is the resistance 0.5 to 2.5 ohm (FULL) and 50 to 52 ohm (EMPTY)? Go to step 8.  Replace the fuel level sensor.
8 CHECK FUEL SUB LEVEL SENSOR. 
  1. Remove the fuel sub level sensor. < Ref. to REMOVAL , Fuel Sub Level Sensor>
  2. Measure the resistance between fuel sub level sensor terminals when setting the float to FULL and EMPTY position.

Terminals 
No. 1 - No. 2: 		 Is the resistance 0.5 to 2.5 ohm (FULL) and 42 to 44 ohm (EMPTY)? Go to step 9.  Replace the fuel sub level sensor.
9 CHECK HARNESS BETWEEN FUEL SUB LEVEL SENSOR AND COMBINATION METER. 
  1. Disconnect the connector from combination meter.
  2. Measure the resistance between fuel sub level sensor harness connector terminal and combination meter harness connector terminal.

Connector & terminal 
(R58) No. 2 - (i10) No. 3: 		 Is the resistance less than 10 ohm? Go to step 10.  Repair the wiring harness.
10 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. 3 - (R59) No. 2: 		 Is the resistance less than 10 ohm? Go to step 11.  Repair the wiring harness.
11 CHECK FUEL LEVEL SUB SENSOR GROUND CIRCUIT. 
Measure the resistance between fuel level sub sensor harness connector terminal and chassis ground.
Connector & terminal 
(R59) No. 1 - Chassis ground: 		 Is the resistance less than 10 ohm? Check the fuel gauge. < Ref. to , REMOVAL . > Repair the wiring harness.
