Fuel Gauge Sender: Testing and Inspection
Fig. 10 Level Sensor Diagnosis
This procedure tests the resistance of the level sensor itself. It does not test the level sensor circuit.
The level sensor is a variable resistor. Its resistance changes with the amount of fuel in the tank.
The float arm attached to the sensor moves as the fuel level changes. To test the level sensor, connect an ohmmeter across the sensor signal and sensor
ground terminals of the fuel pump module connector. Move the float lever to the positions shown in the resistance chart. Record the resistance at each
point. Replace the level sensor if the resistance is not within specifications.
