P1409 Code - EGR Vacuum Regulator Solenoid Circuit Malfunction
Quick Answer
This test checks the electrical function of the Exhaust Gas Recirculation Vacuum Regulator (EGRVR) solenoid. Common causes include Faulty Exhaust Gas Recirculation Vacuum Regulator (EGRVR) solenoid, EGR Vacuum Regulator Solenoid harness is open or shorted, EGR Vacuum Regulator Solenoid circuit poor electrical connection. 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.
