Honda HR-V: Fuel Gauge Sending Unit Test (AWD)

Test

1. Fuse - Check

1. Check the No. B21 (10 A) +B BACK UP fuse in the under-hood fuse/relay box and the No. C34 (7.5 A) IG1 METER fuse in the under-dash fuse/relay box before testing.

2. Body Electrical DTCs - Check

1. Check for body electrical system DTCs.
   • If no problem is found, go to the next procedure.
   • If DTC B1175 or B1176 is indicated, go to the indicated DTC's troubleshooting.

5. Access Panel - Remove

1. Remove the access panel (A) from the floor
2. Disconnect the connector (B).

6. Open or Short Wire at Fuel Gauge Sending Unit Connector - Check

1. Measure the voltage between fuel tank unit connector terminals No. 2 and No. 4 with the vehicle in ON mode. There should be 12 volt battery voltage.
   • If the voltage is OK, go to step 2.
   • If the voltage is not as specified, check for:
     • a short in the GRY wire to ground.
     • an open in the PNK wire.
2. Turn the vehicle to the OFF (LOCK) mode.

7. Fuel Tank Unit - Remove - Refer to: Fuel Tank Unit Removal and Installation (2WD), or Fuel Tank Unit Removal and Installation (AWD)

8. Fuel Gauge Sending Unit - Test

1. Measure the resistance between fuel tank unit 4P connector terminals No. 2 and No. 4 with the float at E (EMPTY), LOW (LOW FUEL INDICATOR) and F (FULL) positions. If you do not get the following readings, replace the fuel tank unit - Refer to: Fuel Tank Unit Removal and Installation (2WD), or Fuel Tank Unit Removal and Installation (AWD).

2. Reconnect the fuel tank unit connector
3. Remove the No. B21 (10 A) +B BACK UP fuse in the under-hood fuse/relay box and the No. C34 (7.5 A) IG1 METER fuse in the under-dash fuse/relay box for at least 10 seconds, then reinstall it
4. Turn the vehicle to the ON mode
5. Check that the pointer of the fuel gauge indicates F with the float at F.
   • If the pointer of the fuel gauge does not indicate F, replace the gauge control module.
   • If the gauge is OK, the test is complete.

NOTE:

• The pointer of the fuel gauge returns to the bottom of the gauge dial when turned the vehicle in the ACCESSORY or OFF (LOCK) mode, regardless of the fuel level.
• Remove the No. B21 (10 A) +B BACK UP fuse in the under-hood fuse/relay box and the No. C34 (7.5 A) IG1 METER fuse in the under-dash fuse/relay box for at least 10 seconds after completing the test, otherwise it may take up to 20 minutes for the fuel gauge to indicate the correct fuel level.
