What P2082 means
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 gasoline 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.
P2082 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2082
- Engine warning lamp on
- Usually no noticeable driving change
Common causes of P2082
- Most likelyECM calibration error on affected Nissan/Infiniti models (reprogramming)
- PossibleBank 2 sensor drifted or contaminated
- Less likelyExhaust leak on bank 2 ahead 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 P2082 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 82 | The exact fault in that area. |
What to do next
- Note P2082 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 P2082
What does P2082 mean?
P2082 means "Exhaust Gas Temperature Sensor Circuit Range/Performance (Bank 2 Sensor 1)". P2082 is the plausibility fault of the first exhaust temperature sensor on bank 2, the cylinder bank without cylinder 1. It is a generic code, so it means the same on every make.
Is it safe to drive with P2082?
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 P2082 fail an emissions test?
Yes, it can. P2082 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 P2082 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. This is a job for a workshop.
Will P2082 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.
