P113C 2015 GMC Sierra Code - Exhaust Gas Temperature Sensor 2 Not Plausible
Quick Answer
The exhaust gas temperature sensors are variable resistors that measure the temperature of the exhaust gas at the inlet and outlet of the diesel oxidation catalyst as well as the inlet and outlet of the Diesel Particulate Filter (DPF). Common causes include Faulty Exhaust Gas Temperature Sensor, Exhaust Gas Temperature Sensor harness is open or shorted, Exhaust Gas Temperature Sensor 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.
