P2214
System
Powertrain (Diesel Emissions)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

NOx Sensor Negative Current Control Circuit Low (Bank 1 Sensor 1)

Understand P2214, common causes, and the right TOPDON scanner to diagnose it.

NOx negative current control low.

Typowe objawy

  • Check engine light
  • Derate

Typowe przyczyny

  • Short in harness
  • Failed NOx sensor
  • Heat damage at 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

What does P2214 mean?
P2214 indicates nox sensor negative current control circuit low (bank 1 sensor 1). NOx negative current control low.
Can I diagnose P2214 with a basic code reader?
P2214 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 P2214?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P2214?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
