Note: See fuel gauge wiring diagram in Chapter. "Body electrical equipment".
1. Before testing, check the INSTRUMENT UGHT (7.5A) fuse in the under-dash fuse/relay box.
2. Remove the inspection panel from the floor.
3. Turn the ignition switch to the OFF position, then disconnect the 5-pin connector from the fuel pump.
4. Measure the voltage between terminals #1 and #2 of the 5-pin fuel pump connector when the ignition key is turned to the ON (II) position. It should be between 5 and 8 V.
- If the voltage is within normal limits, proceed to step 6.
- If the voltage is different from the norm, check:
- Is there a break in the BLACK-YELLOW or BLACK wire?.
- poor grounding (G501).
5. Turn the ignition key to the OFF position.
6. Connect a jumper wire between terminals No.1 and No.2 of the 5-pin fuel pump connector, then turn the ignition switch to the ON (II) position.
7. Make sure that the fuel gauge needle starts to move towards the "F" mark.
- If the gauge needle does not move at all, replace the fuel gauge.
- If the fuel gauge is OK, check the fuel gauge sensor.
Note:
- Before the needle reaches the "F" mark on the gauge scale, turn the ignition key to the OFF position. Failure to do so may damage the gauge.
- The fuel gauge is a coil type, therefore the fuel level is displayed continuously even when the ignition key is turned to the OFF position and the needle moves slower than the bimetal type gauge.
