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

NOx Sensor Performance (Bank 2 Sensor 1)

Understand P2224, common causes, and the right TOPDON scanner to diagnose it.

Bank 2 upstream NOx sensor performance out of spec.

Typowe objawy

  • P20EE may accompany
  • SCR warning

Typowe przyczyny

  • Failed NOx sensor
  • SCR catalyst degraded
  • DEF not injecting properly

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

Często zadawane pytania

What does P2224 mean?
P2224 indicates nox sensor performance (bank 2 sensor 1). Bank 2 upstream NOx sensor performance out of spec.
Can I diagnose P2224 with a basic code reader?
P2224 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for P2224?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P2224?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
