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 short-circuited
- Poor electrical connection in Bank 2 Sensor 2 Exhaust Gas Temperature Sensor circuit
- Exhaust leaks
- Excessive particulate buildup on the sensor
How to Fix Code P247D
Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P247D Meaning
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 to voltage, sending it back to the PCM with the voltage signal to control engine conditions for effective emission reduction. The PCM sets the OBDII code P247D when the exhaust gas temperature sensor is outside factory specifications.
