Fuel Gauge Test

CAUTION: In Step 3), turn ignition off before fuel gauge pointer reaches "F" mark. Failure to turn ignition off before pointer reaches "F" mark may damage fuel gauge.
  1. Ensure ignition switch is in OFF position. Check fuse No.13 (10-amp) in dash fuse box. If fuse is okay, remove luggage compartment carpet. Remove access panel. Disconnect 5-pin connector from fuel gauge sending unit.
  2. Connect voltmeter positive lead to Yellow/Green wire and negative lead to body ground. Turn ignition switch to ON position. Indicated voltage should be 5-8 volts. If voltage is not as specified, check for open circuit in Yellow and/or Yellow/Green wire. Check for poor ground connection.
  3. Turn ignition switch to OFF position. Connect Yellow/Green and Yellow/White wires with a jumper wire. Turn ignition switch to ON position. Ensure fuel gauge pointer starts to move toward "F" mark on gauge. If fuel gauge pointer does not move, replace gauge. If fuel gauge is okay, check sending unit.
