Code P1407 2016 Chevrolet Silverado Description
The P1407 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the Exhaust Gas Recirculation (EGR) control circuit being shorted. The EGR system is responsible for recirculating a portion of the exhaust gases back into the engine's intake manifold to reduce harmful emissions and control combustion temperatures. The EGR control circuit manages the operation of the EGR valve, which opens and closes to regulate the flow of exhaust gases.
Common Causes of P1407 2016 Chevrolet Silverado
- Wiring harness damage or corrosion
- Faulty EGR control solenoid
- EGR valve stuck open or closed
- Poor electrical connection at EGR components
- ECM (Engine Control Module) malfunction
Symptoms of P1407 2016 Chevrolet Silverado
- Check engine light illuminated
- Reduced engine performance
