Fuel Gauge Sender: Testing and Inspection
Fuel Gauge Sending Unit Test
NOTE: For the fuel gauge system circuit diagram, refer to the Gauges Circuit Diagram.
1. Before starting the fuel gauge sending unit test, do the B-CAN system diagnosis Test Mode A troubleshooting.
-
If no problem is found, go to step 2.
-
If DTC B1175 is indicated, go to the indicated DTC troubleshooting.
2. Check the No.21 METER (7.5 A) fuse in the under-dash fuse/relay box before testing.
3. Do the gauge self-diagnostic function.
-
If the fuel gauge needle sweeps from the minimum to maximum position and then returns to minimum, the gauge is OK. Go to step 4.
-
If the fuel gauge needle does not sweep correctly, replace the gauge control module and retest.
4. Turn the ignition switch OFF.
5. Remove the trunk floor.
6. Remove the access panel (A) from the floor.
7. Disconnect the fuel pump 5P connector (B).
8. Remove the fuel tank unit from the fuel tank.
9. Measure resistance between the No.1 and No.2 terminals with the float at E (EMPTY), 1/2 (HALF FULL), and F (FULL) positions.
