Code P2482 GMC Description

The P2482 GMC code indicates an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit on Bank 1 Sensor 5. The EGT sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. When the sensor detects a high voltage signal, it triggers this diagnostic trouble code (DTC). This can lead to various performance issues and potentially cause long-term damage if not addressed promptly.
