P2483: Exhaust Gas Temperature Sensor Circuit Range or Performance Bank 1 Sensor 5
Same as P242B on bank 1 sensor 5.
What P2483 means
P2483 is a generic OBD-II powertrain code in the emissions group. In plain English: the signal is within electrical limits but doesn’t make sense compared with other readings, so the part or system isn’t performing as expected. Bank 1 is the side of the engine with cylinder 1 (inline engines only have bank 1).

- Emissions-related
- Yes — can fail inspection
- Limp mode possible

Common causes
- 01Sensor element driftedMost likely
Can I drive with P2483?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. Left alone it can raise fuel use and emissions and will fail an OBD inspection. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
- Emissions-related: will usually fail an OBD inspection
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2483
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2483. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.

Check for related codes first
Look for P2488, P2474, P2467, P242B. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Test the circuit
Inspect the wiring and connector at the egt sensor (bank 1, sensor 5) for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Sensor element drifted. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2483 FAQ
What does P2483 mean?
P2483 means “Exhaust Gas Temperature Sensor Circuit Range or Performance Bank 1 Sensor 5”. Same as P242B on bank 1 sensor 5.
Is P2483 serious? Can I keep driving?
We rate P2483 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. Left alone it can raise fuel use and emissions and will fail an OBD inspection. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2483?
The most common causes, from most to least likely: Sensor element drifted. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2483?
Typical labor is about $75–$225 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2483 myself?
DIY difficulty is moderate. Many owners can handle it with a scan tool, a multimeter and basic hand tools. Always confirm the cause before buying parts.
Will P2483 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
