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.

Sintomi comuni

  • Check engine light
  • Derate

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
