P2482
Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 5
Auxiliary emissions (exhaust temperature)
Generic OBD-II
Low
What it means
P2482 means the ECM sees a high signal voltage from exhaust gas temperature (EGT) sensor 5 on bank 1, usually from an open circuit or a short to voltage. This sensor reports exhaust temperature for catalyst and particulate-filter protection. The engine keeps running normally, so this is primarily an emissions and exhaust-monitoring concern rather than a drivability one.
Low
Can I keep driving? Yes — the car drives normally; this is an exhaust-temperature sensor circuit fault, not a running problem.
Common symptoms
What you'll notice
- Check-engine light on
- Usually no change in how the car drives
- Possible disruption to DPF regeneration on diesels
- May fail an emissions/readiness test
Common causes
Most likely first
- Open circuit or short to voltage in the EGT sensor 5 wiring (drives the signal high)Likely
- Faulty exhaust gas temperature (EGT) sensor 5 on bank 1Common
- Corroded or loose sensor connectorCommon
- Heat-damaged harness near the exhaustLess often
- Faulty ECM/PCM input (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the sensor signal is reading high.
- Inspect EGT sensor 5 on bank 1 and its connector for corrosion, damage, or a loose fit.
- Check the circuit for an open or a short to voltage that would pull the signal high.
- Measure the sensor's resistance against spec; replace it if out of range.
- Clear the code and re-drive; if the signal stays high with wiring verified, replace the sensor.
FAQ
Quick answers
Is it safe to drive with P2482?+
Yes for normal driving. It's an emissions-monitoring sensor fault, not an engine problem, but fix it to keep exhaust-temperature protection working and stay emissions-legal.
Can I just clear P2482?+
You can, but an open circuit or bad sensor will set it again. Repair the wiring or sensor first.
