P041D 2016 Chevrolet Silverado Code - Exhaust Gas Recirculation Temperature Sensor 1 Circuit High 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.

Symptoms may include the Check Engine Light turning on, reduced engine performance, poor fuel efficiency, and possible engine hesitation or rough idling.
3. What causes the P041D code to appear?
Possible causes include a faulty EGR temperature sensor, wiring or connector issues in the EGR circuit, or a malfunctioning engine control module (ECM).
4. Can I drive my 2016 Chevrolet Silverado with a P041D code?
It’s not recommended to drive for an extended period with this code, as it can lead to reduced engine performance and potential damage to the EGR system or other components.
5. How do I diagnose the P041D code?
Start by scanning the vehicle for codes, inspecting the EGR temperature sensor and its wiring for damage, and testing the sensor's voltage and resistance with a multimeter.
6. How do I fix the P041D code on my Silverado?
Repairs may include replacing the EGR temperature sensor, repairing or replacing damaged wiring or connectors, or reprogramming/updating the ECM if necessary.
7. How much does it cost to repair a P041D code?
The cost can vary, but replacing the EGR temperature sensor typically ranges from $100 to $300, including parts and labor.
8. What tools are needed to repair the P041D code?
You’ll need a diagnostic scan tool, a multimeter, and basic hand tools for accessing and replacing the EGR temperature sensor.
9. Can a dirty EGR valve cause the P041D code?
A dirty or clogged EGR valve is unlikely to directly cause this code but may contribute to related performance issues. Cleaning or inspecting it is still a good idea.
10. Does the P041D code require ECM replacement?
ECM replacement is rarely needed for this code. It should only be considered if all other components test fine and the ECM fails diagnostics.
