P041B 2017 GMC Sierra Code - Exhaust Gas Recirculation Temperature Sensor 1 Performance
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 1, Exhaust Gas Recirculation Temperature Sensor 1 harness is open or shorted, Exhaust Gas Recirculation Temperature 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.
