Understand P2472, common causes, and the right TOPDON scanner to diagnose it.

Primary EGT sensor circuit low.

Typowe objawy

  • Regen inop
  • False overheat or underheat readings

Typowe przyczyny

  • Short in EGT harness
  • Failed probe
  • Heat damage at turbo area 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
