P2483
Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 5
Exhaust gas temperature (EGT) sensor
Generic OBD-II
Low
What it means
P2483 means the bank 1, sensor 5 exhaust gas temperature (EGT) sensor is reading outside its expected range or not tracking as the ECM expects. Engines with several EGT sensors use them to protect and control the exhaust after-treatment, so the car still drives normally, but a bad reading can disable regeneration or force reduced-power protection on a diesel.
Low
Can I keep driving? Yes — the car runs normally; the main risk is disabled after-treatment regeneration or reduced-power protection, so repair it before it affects the exhaust system.
Common symptoms
What you'll notice
- Check-engine light on
- Often no noticeable driving symptom
- On diesels, disabled regeneration or reduced-power protection
- Implausible exhaust-temperature reading on a scan tool
Common causes
Most likely first
- Faulty exhaust gas temperature sensor (bank 1, sensor 5)Likely
- Heat-damaged wiring or connector near the exhaustCommon
- Poor or corroded electrical connectionCommon
- Sensor reading out of range versus the other EGT sensorsLess often
- Rarely, an ECM faultLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare all EGT sensor readings at key-on.
- Inspect the sensor-5 connector and harness for heat damage or chafing.
- Measure sensor resistance and compare to specification.
- Replace the EGT sensor if it reads out of range.
- Clear the code and re-test, watching the live temperature value.
FAQ
Quick answers
Is it safe to drive with P2483?+
Yes — it's a temperature-monitoring sensor fault, not a no-start. The concern is disabled regeneration on a diesel, so have it repaired before long.
Can I just clear P2483?+
It returns once the ECM re-checks the sensor unless the sensor, wiring, or connector is repaired.
