P113F Cadillac Code - Exhaust Gas Temperature Sensor 5 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.

Code P113F Cadillac Description

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). The Engine Control Module (ECM) supplies a bias 5-volt signal to the exhaust gas temperature sensor signal circuit and supplies a ground to the low reference circuit. The exhaust gas temperature information is used by the ECM during the particulate filter cleaning process. The following table illustrates the relationship between the temperature of the exhaust gas and the resistance and voltage of the exhaust gas temperature sensor. The Diagnostic Trouble Code (DTC) will be set if the ECM detects an exhaust gas temperature value that is not plausible when the ignition is switched on.
