NOTE: For the fuel gauge system circuit diagram, refer to the Gauges Circuit Diagram. Before starting the fuel gauge sending unit test, perform the multiplex integrated control system troubleshooting test mode A. If no problem is found, go to Step 2 . If DTC B1175 is indicated, go to the indicated DTC troubleshooting. Check the No. 21 METER (7.5 A) fuse in the under-dash fuse/relay box before testing. Do the gauge drive circuit check. If the fuel gauge needle sweeps from the minimum to maximum position and then returns to minimum, the gauge is OK. Go to Step 3 . If the fuel gauge needle does not sweep correctly, replace the gauge assembly and retest. Turn the ignition switch OFF. Remove the trunk floor. Remove the access panel (A) from the floor. Disconnect the fuel pump 5P connector (B). Except ECONO model: Remove the fuel pump assembly from the fuel tank. ECONO model: Remove the fuel pump assembly from the fuel tank. |
