P2082Exhaust Gas Temperature Sensor Circuit Range/Performance (Bank 2 Sensor 1)
- 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
- P2082 is the plausibility fault of the first exhaust temperature sensor on bank 2, the cylinder bank without cylinder 1. It only exists where both banks carry separate sensors ahead of the merge point, which in practice means V-type petrol engines with turbo or catalyst protection. The diesel tables from GM, Ford and VW number every sensor on bank 1 because one aftertreatment line serves the engine. Nissan is the documented user: bulletins NTB16-124 and ITB16-051 cover the 2017 Armada, Titan and QX80 with the VK56VD, where P2080 and/or P2082 came on although the sensors were fine; the cure is new ECM software, and the bulletin explicitly says not to replace the sensor. ITB17-050 does the same for the Q50 and Q60 with the VR30DDTT. Nissan does not publish the thresholds. Jumping values on this sensor are P2083.
- What you may notice
- Engine warning lamp on
- Usually no noticeable driving change
- Likely causes
- LikelyECM calibration error on affected Nissan/Infiniti models (reprogramming)
- PossibleBank 2 sensor drifted or contaminated
- RareExhaust leak on bank 2 ahead of the sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
