NOx Sensor Heater Control Circuit Low (Bank 2 Sensor 1)

Understand P2207, common causes, and the right TOPDON scanner to diagnose it.

Bank 2 NOx heater circuit low.

Typowe objawy

  • SCR warning
  • Cold start NOx fault

Typowe przyczyny

  • Failed NOx heater bank 2
  • Wiring fault
  • Exhaust heat damage

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
