P2083 code meaning
Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 2 Sensor 1)
Powertrain system Generic code P20xx codes Check engine light
What P2083 means
P2083 reports an unsteady signal from exhaust temperature sensor 1 on bank 2: the value changes by more than the exhaust can physically manage between two readings, or briefly drops out. Only one maker documents it publicly. Infiniti bulletin ITB17-050 lists P2083 with P0544–P0549 and P2080–P2082 for Infiniti's Q50 (model years 2016–2017) and Q60 (2017) with the 3.0 L VR30DDTT twin-turbo V6, which has one sensor per bank, and prescribes an ECM reprogram. Ford's 2014 gasoline code list includes P2083 with a lamp marker. No threshold is published for bank 2; GM's bank 1 counterpart P2081 shows the usual approach of counting fast steps in a window of samples. Before replacing parts, wiggle-test the connector and lead while watching live data. A plausible but wrong steady value would be P2082.
P2083 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 repairWhen cleared with a scanner
Symptoms of P2083
- Engine warning lamp on
- Bank 2 exhaust temperature flickering in live data
Common causes of P2083
- Most likelyIntermittent contact in the bank 2 sensor connector
- PossibleECM software (Infiniti VR30DDTT bulletin)
- PossibleLead damaged by turbocharger or exhaust heat
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2083 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. |
| 83 | The exact fault in that area. |
What to do next
- Note P2083 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 P2083
What does P2083 mean?
P2083 means "Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 2 Sensor 1)". P2083 reports an unsteady signal from exhaust temperature sensor 1 on bank 2: the value changes by more than the exhaust can physically manage between two readings, or briefly drops out. It is a generic code, so it means the same on every make.
Is it safe to drive with P2083?
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 P2083 fail an emissions test?
Yes, it can. P2083 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 P2083 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. This is a job for a workshop.
Will P2083 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
