P2087 GMC Code - Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2

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 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. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P2087 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 P2087 OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.
