P040E 2014 Chevrolet Silverado Code - Exhaust Gas Recirculation Temperature Sensor 2 Circuit Erratic
Quick Answer
The Exhaust Gas Recirculation (EGR) temperature sensors are variable resistors that measure the temperature of the exhaust gas at the inlet and outlet of the EGR cooler. Common causes include Faulty Exhaust Gas Recirculation (EGR) Temperature Sensor 2, Exhaust Gas Recirculation Temperature Sensor 2 harness is open or shorted, Exhaust Gas Recirculation Temperature Sensor 2 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.
