P2485 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 P2485 OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
