P247A GMC Code - Exhaust Gas Temperature Out of Range Bank 1 Sensor 3
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 3, Exhaust Gas Temperature Sensor Bank 1 Sensor 3 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 1 Sensor 3 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
