NOx Sensor Positive Current Control Circuit Open (Bank 2 Sensor 1)

Understand P2212, common causes, and the right TOPDON scanner to diagnose it.

Bank 2 NOx positive current control open.

Veelvoorkomende symptomen

  • SCR codes bank 2
  • Check engine light

Typische oorzaken

  • Failed bank 2 NOx sensor
  • Open circuit
  • Connector at exhaust

Welke scanner heb je nodig?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
