What P2214 means
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).
P2214 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.8 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2214
- Malfunction indicator lamp on
- Often stored with P2201 or SCR efficiency code P20EE
- Higher DEF consumption or SCR warning
Common causes of P2214
- Most 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
- Less likelyExhaust leak upstream of the sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2214 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 14 | The exact fault in that area. |
What to do next
- Note P2214 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2214
What does P2214 mean?
P2214 means "NOx Sensor Circuit Range/Performance (Bank 2)". Under J2012, P2214 is the plausibility fault of the bank 2 NOx sensor: wiring intact, reading not credible. It is a generic code, so it means the same on every make.
Is it safe to drive with P2214?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2214 fail an emissions test?
Yes, it can. P2214 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2214 to fix?
Difficulty: medium. A typical repair takes 0.8 to 3 hours of work. This is a job for a workshop.
Will P2214 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
