P247A - Exhaust Gas Temperature Out of Range Bank 1 Sensor 3

Repair Importance Level: 2/3
Repair Difficulty Level: 2/3

Possible causes

  • 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
  • Exhaust leaks
  • Excessive particulate matter buildup on sensor
  • Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • P247a 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 P247A OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
