Fuel Sender Circuit Failure

Understand B1200, common causes, and the right TOPDON scanner to diagnose it.

Fuel level sender circuit fault — erratic or empty fuel gauge.

Veelvoorkomende symptomen

  • Fuel gauge reads empty/full incorrectly
  • Low fuel warning wrong

Typische oorzaken

  • Failed fuel level sender
  • Open in fuel pump module harness
  • Corrosion at tank connector

Welke scanner heb je nodig?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
