Exhaust Gas Temperature Sensor Circuit High (Bank 1 Sensor 1)

Understand P2473, common causes, and the right TOPDON scanner to diagnose it.

Primary EGT sensor circuit high or open.

Typowe objawy

  • DPF codes
  • Check engine light

Typowe przyczyny

  • Open EGT circuit
  • Failed sensor
  • Broken wire at exhaust flex pipe

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
