Fuel Gauge Sending Unit TestNOTE: For the fuel gauge system circuit diagram, refer to the gauges circuit diagram.
|1.||Check the No. 3 (7.5 A) fuse in the under-dash fuse/relay box before testing.|
|2.||Turn the ignition switch OFF.|
|3.||Remove the access panel from the floor.|
|4.||Disconnect the fuel pump 5P connector.|
|5.||Measure voltage between fuel pump 5P connector terminals No. 1 and No. 2 with the ignition switch ON (II). There should be battery voltage.|
|6.||Turn the ignition switch OFF.|
|7.||Install a 2 W resistor between fuel pump 5P connector terminals No. 1 and No. 2, then turn the ignition switch ON (II).|
|8.||Check that the pointer of the fuel gauge indicates ‘‘F''.|
NOTE: The pointer of the fuel gauge returns to the bottom on the gauge dial when the ignition switch is OFF regardless of the fuel level.
|9.||Remove the fuel tank unit.|
|10.||Measure the resistance between No. 1 and No. 2 terminals with the float at E (EMPTY), 1/2 (HALF FULL), and F (FULL) positions.|
If you do not get the following readings, replace the fuel gauge sending unit.
