Check Fuel Level Sensor

CHECKING FUEL LEVEL SENSOR

Step	Check	Yes	No
1 CHECK FUEL LEVEL SENSOR. Remove the fuel level sensor. < Ref. to REMOVAL , Fuel Level Sensor. > 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 2 .	Replace the fuel level sensor.
2 CHECK FUEL SUB LEVEL SENSOR. Remove the fuel sub level sensor. < Ref. to REMOVAL , Fuel Sub Level Sensor. > 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 3 .	Replace the fuel sub level sensor.
3 CHECK HARNESS BETWEEN FUEL SUB LEVEL SENSOR AND COMBINATION METER. Disconnect the connector from combination meter. Measure the resistance between fuel sub level sensor harness connector terminal and combination meter harness connector terminal. Connector & terminal (R59)No. 1-(i11)No. 1:	Is the resistance less than 10 ohm?	Go to step 4 .	Repair the wiring harness.
4 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 5 .	Repair the wiring harness.
5 CHECK FUEL LEVEL SENSOR GROUND CIRCUIT. Measure the resistance between fuel level sensor harness connector terminal and chassis ground. Connector & terminal (R58) No. 2 - Chassis ground:	Is the resistance less than 10ohm?	Check the fuel gauge. < Ref. to REMOVAL , Fuel Gauge. >	Repair the wiring harness.
