Fuel Gauge Sender: Testing and Inspection
SENDING UNIT TEST
NOTE: When a problem occurs with a cluster gauge -- before disassembling the cluster to check the gauge -- check for a defective sending unit, sending
unit wiring, or body control module.
Sending units and wiring can be checked by grounding the connector leads at the sending unit.
With the ignition ON grounding the the sending unit wire will cause the fuel or temperature gauge to read at or above maximum. (For fuel sending
units this is the center terminal of the Fuel pump module connector.)
The following procedure tests the resistance of the level sensor. It does not test the 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
fluid level changes.
1. To test the level sensor connect an ohmmeter between the sensor signal terminal and the ground terminal of the fuel pump module connector. (The
middle terminal and the terminal farthest away from the middle terminal.)
2. Move the float lever to the full position and empty position and note the resistance at both points.
3. Replace the sensor if the resistance is not within the specified values.
-
Sensor Full Position 8 ohms maximum
-
Sensor Empty Position 96.5 - 108.0 ohms
