IG "OFF".
Disconnect Fuel Level Sensor harness connector.

Measure the resistance between terminal 1 and 3 of Fuel Level Sensor harness connector. (Component side) (Measure the resistance while changing the float position.)

Fig 1: Measuring Resistance Between Terminal 1 And 3 Of Fuel Level Sensor Connector

Is the measured resistance within specification ?
YES : --> Substitute with a known-good ECM/PCM and check for proper operation. If the problem is corrected, replace ECM/PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NO : --> Substitute with a known-good Fuel Level Sensor and check for proper operation. If the problem is corrected, replace Fuel Level Sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
