P2082
Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 2 Sensor 1
Auxiliary emissions control
Generic OBD-II
Low
What it means
P2082 means the engine computer sees exhaust gas temperature (EGT) sensor 1 on bank 2 reading outside its expected range — a value that doesn't match conditions rather than a hard open or short. This sensor protects the turbo and catalyst and, on diesels, helps manage particulate-filter regeneration. The car drives normally; the main effect is a check-engine light.
Low
Can I keep driving? Yes — the engine runs and starts normally; this is an emissions-monitoring sensor, so drive to a repair at your convenience.
Common symptoms
What you'll notice
- Check-engine light on
- Usually no noticeable change in how the car drives
- On diesels, delayed or interrupted DPF regeneration
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor, bank 2 sensor 1, reading implausiblyLikely
- Open or high-resistance connection in the EGT sensor harnessCommon
- Corroded or loose connector at the sensorCommon
- Damaged wiring routed near hot exhaust componentsLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare the sensor's reading to the other EGT sensors at the same temperature.
- Inspect the EGT sensor connector and wiring for heat damage, corrosion, or high resistance.
- Check the circuit against the wiring diagram for opens or poor connections; repair as needed.
- Replace the EGT sensor if it reads out of range against spec. Clear the code and re-test.
FAQ
Quick answers
Is it safe to drive with P2082?+
Yes. This sensor monitors exhaust temperature for emissions and turbo/DPF protection; the car drives normally, but address it before long on a diesel.
Can I just clear P2082?+
It returns until the sensor or its wiring is repaired.
