Check Fuel Level Sensor

CHECK STEP FOR FUEL LEVEL SENSOR

Step	Check	Yes	No
1 CHECK FUEL LEVEL SENSOR. Remove the fuel level sensor. <Ref. to REMOVAL , Fuel Level Sensor.> or <Ref. to REMOVAL , Fuel Level Sensor.> or refer to "FU(STI) Section". Measure the resistance between fuel level sensor terminals when the float is in FULL or EMPTY position. Terminals No. 2 - No. 3:	Is the resistance 0.5 - 2.5 Ω (FULL) and 50 - 52 Ω (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.> or <Ref. to REMOVAL , Fuel Sub Level Sensor.> or refer to "FU(STI) Section". 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 0.5 - 2.5 Ω (FULL) and 42 - 44 Ω (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 the combination meter. Measure the resistance between the fuel sub level sensor harness connector terminal and combination meter harness connector terminal. Connector & terminal Except for STI model (R59) No. 1 - (i12) No. 2: STI model (R59) No. 1 - (i12) No. 3:	Is the resistance less than 10 Ω?	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 Ω?	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 10 Ω?	Except for STI model: Check the fuel gauge. <Ref. to REMOVAL , Fuel Gauge.> STI model: Replace the meter main assembly.	Repair the wiring harness.
