P2213 NOx Sensor Circuit (Bank 2)

P2213 mirrors P2200 for the second cylinder bank: the NOx sensor serving bank 2 ahead of its SCR catalyst reports a general electrical fault. That presumes an engine whose banks feed separate aftertreatment lines. No manufacturer documents P2213 publicly; even V8 diesels such as GM's 6.6L Duramax, Ford's 6.7L and the Cummins 5.0L in Nissan's Titan XD route both banks into a single SCR line and use bank 1 codes only. As a guide, GM's LML logs P2200 when the smart sensor keeps signalling an interrupted wire for 0.5 or 10 s, and Ford adds probe-line shorts and checksum errors inside the sensor controller. CARB requires circuit faults on NOx sensors to be caught. P2214 to P2217 cover the other bank 2 signal faults.

Likely causes

Internal fault in the bank 2 NOx probe or its sensor control unit
Heat-damaged or chafed lead between probe and sensor control unit
Water or corrosion in the bank 2 sensor connector

Symptoms

  • Malfunction indicator lamp on
  • No NOx value from the bank 2 sensor in live data
  • SCR warning, possibly with an inducement countdown
