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.

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

Typowe przyczyny

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

Jakiego skanera potrzebujesz?

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

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników
