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

Understand P2213, common causes, and the right TOPDON scanner to diagnose it.

NOx sensor negative current control open.

Vanliga symptom

  • NOx readings invalid
  • SCR inactive

Typiska orsaker

  • Failed sensor internal cell
  • Wiring open
  • SCR control module fault

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer

Vanliga frågor

What does P2213 mean?
P2213 indicates nox sensor negative current control circuit open (bank 1 sensor 1). NOx sensor negative current control open.
Can I diagnose P2213 with a basic code reader?
P2213 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 P2213?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P2213?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
