P1407 2016 GMC Sierra Code - Exhaust Gas Recirculation Control Circuit Shorted
Quick Answer
The P1407 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Exhaust Gas Recirculation (EGR) control circuit being shorted. Common causes include Faulty EGR Valve: A faulty EGR valve that is stuck open or closed can cause the EGR control circuit to short, EGR Solenoid Malfunction: A malfunctioning EGR solenoid can prevent the proper operation of the EGR system, leading to a short in the control circuit, Wiring Issues: Damaged or corroded wiring in the EGR control circuit can cause a short circuit. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1407 2016 GMC Sierra Description
The P1407 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Exhaust Gas Recirculation (EGR) control circuit being shorted. The EGR system is responsible for reducing nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine's intake system. When the EGR control circuit is shorted, it means that there is an electrical issue preventing the proper operation of the EGR system.
Common Causes of P1407 2016 GMC Sierra
- Faulty EGR Valve: A faulty EGR valve that is stuck open or closed can cause the EGR control circuit to short.
- EGR Solenoid Malfunction: A malfunctioning EGR solenoid can prevent the proper operation of the EGR system, leading to a short in the control circuit.
- Wiring Issues: Damaged or corroded wiring in the EGR control circuit can cause a short circuit.
- ECM Malfunction: A malfunction in the Engine Control Module can also disrupt the EGR control circuit, triggering the P1407 code.
Symptoms of P1407 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P1407 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idling: A malfunctioning EGR system can cause the engine to idle roughly or even stall at times.
- Decreased Fuel Efficiency: A shorted EGR control circuit can lead to decreased fuel efficiency as the engine may not be operating at its optimal performance.
- Increased Emissions: The vehicle may fail emissions tests or emit higher levels of pollutants due to the malfunctioning EGR system.
How to Fix P1407 2016 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the DTC and further diagnose the exact cause of the shorted EGR control circuit.
- Inspect EGR Components: Check the EGR valve, EGR solenoid, and wiring harness for any signs of damage or malfunction.
- Repair or Replace Components: Depending on the diagnosis, repair or replace the faulty EGR components causing the short circuit.
- Clear Codes: Clear the DTC from the vehicle's ECM using the scan tool after the repair is completed.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the Check Engine Light does not reappear.
Cost to Fix P1407 2016 GMC Sierra
