P2214NOx Sensor Circuit Range/Performance (Bank 2)

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
Under J2012, P2214 is the plausibility fault of the bank 2 NOx sensor: wiring intact, reading not credible. No maker uses it that way in public documents. Hino does use the number differently: on its J08E inline six (Hino 238, 258, 268 and 338 conventional models, 2011 to 2016) P2214 belongs to NOx sensor 2 behind the SCR catalyst. Hino bulletin SB-14-029 first checks DEF concentration (31.8 to 33.2 percent), exhaust leaks, temperature and airflow sensors and the dosing injector, then re-tests at a steady 45 to 50 mph after a regeneration. SB-15-038 and SB-16-002 link P2214 and P2201 to NOx heater elements cracked by condensation and add DCU software. For a real bank 2 sensor, P2201 logic applies (VW: 60 percent deviation).
What you may notice
  • Malfunction indicator lamp on
  • Often stored with P2201 or SCR efficiency code P20EE
  • Higher DEF consumption or SCR warning
Likely causes
  • LikelyAged or poisoned NOx element reading with offset or slow response
  • PossibleSensor heater cracked by condensation (Hino 2015-2016, SB-15-038/SB-16-002)
  • PossibleDiluted DEF or faulty dosing injector distorting the NOx reading
  • RareExhaust leak upstream of the sensor
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
