P247C Code - Exhaust Gas Temperature Out of Range Bank 2 Sensor 1

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 2 Sensor 1, Exhaust Gas Temperature Sensor Bank 2 Sensor 1 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 Sensor 1 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.

What it means: P247C indicates Exhaust Gas Temperature Out of Range Bank 2 Sensor 1.
Common causes: Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 1, Exhaust Gas Temperature Sensor Bank 2 Sensor 1 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 Sensor 1 circuit poor electrical connection.
Severity: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P247C Description

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF). The EGTS detects exhaust gas temperature and converts it into a voltage and feeds back to the PCM with the voltage signal in order to control engine conditions to effectively reduce emissions. The PCM sets the P247C OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
