P247D Code: Meaning, Causes, and Symptoms | OBD2 Codes
P247D – Exhaust Gas Temperature Out of Range Bank 2 Sensor 2
P247D Possible Symptoms
Engine Light ON (or Service Engine Soon Warning Light)
P247D Possible Causes
Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2,Exhaust Gas Temperature Sensor Bank 2 Sensor 2 harness is open or shorted,Exhaust Gas Temperature Sensor Bank 2 Sensor 2 circuit poor electrical connection,Exhaust leaks,Excessive particulate matter buildup on sensor
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 P247D OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
