7. 문제 해결

If you experience issues with your fuel level gauge, refer to the following common problems and solutions:

• Gauge Not Working (No Reading):
  • Check power supply to the gauge (red wire). Ensure it receives 12V when the ignition is on.
  • Verify the ground connection (black wire) is secure and free of corrosion.
  • Inspect the connection to the fuel sending unit (yellow wire).
  • Test the fuel sending unit for proper resistance range. A faulty sending unit will prevent accurate readings.
• 부정확한 판독:
  • Ensure the fuel sending unit's float arm moves freely within the fuel tank and is not obstructed.
  • Verify the sending unit is correctly calibrated for your tank depth.
  • Check for stable power and ground connections to the gauge. Fluctuations can affect accuracy.
• Gauge Illumination Not Working:
  • Check the wiring for the illumination circuit (if separate from main power).
  • Ensure your vehicle's dashboard lights are functioning correctly.

If these steps do not resolve the issue, it is recommended to consult a qualified automotive electrician.
