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.

Sintomi comuni

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

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
