P041C Chevrolet Code - Exhaust Gas Recirculation Temperature Sensor 1 Circuit Low Voltage

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.

Code P041C Chevrolet Description

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. The Engine Control Module (ECM) supplies 5 volts to the EGR temperature sensor signal circuit and a ground for the low reference circuit. When the EGR temperature sensor is cold, the sensor resistance is high. When the EGR temperature increases, the sensor resistance decreases. The ECM detects a higher voltage on the EGR temperature signal circuit with high sensor resistance. With lower sensor resistance, the ECM detects a lower voltage on the EGR temperature signal circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the EGR temperature sensor resistance is less than 147 Ω for greater than 5 s.
