P2083 GMC Code - Exhaust Gas Temperature Sensor Circuit Intermittent 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 High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2083 GMC 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 P2083 OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
