P2223
System
Powertrain (Diesel Emissions)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

NOx Sensor Current High (Bank 2 Sensor 1)

Understand P2223, common causes, and the right TOPDON scanner to diagnose it.

Bank 2 NOx sensor current high.

Typowe objawy

  • Check engine light
  • Derate on heavy diesel

Typowe przyczyny

  • Failed sensor
  • Internal NOx cell short
  • Module fault

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
