What is a EGR vacuum regulator solenoid?

The EGR vacuum regulator solenoid is an electromagnetic device which is used to regulate the vacuum supply to the EGR valve. The solenoid contains a coil which magnetically controls the position of a disc to regulate the vacuum.

What does the error code p1409 mean on a vacuum regulator?

Table of Contents. Error Code P1409 is defined as EGR Vacuum Regulator Solenoid Circuit Malfunction. This error code refers to a test to check the electrical function of the EGRVR (Exhaust Gas Recirculation Vacuum Regulator) solenoid.

What causes an EGR vacuum regulator to malfunction?

Possible Causes. Many factors may cause this error code to arise. Some of the possible causes are: Defective EGRVR solenoid. Open or shorted EGR vacuum regulator solenoid harness. Poor electrical connection in EGR vacuum regulator solenoid circuit. Defective PCM (rare)

What was the cause of the Ford p1409 accident?

P1409 FORD Possible Causes 1 Faulty Exhaust Gas Recirculation Vacuum Regulator (EGRVR) solenoid 2 EGR Vacuum Regulator Solenoid harness is open or shorted 3 EGR Vacuum Regulator Solenoid circuit poor electrical connection 4 Damaged Powertrain Control Module (PCM)

When does the EGR VR solenoid test fail?

This test checks the electrical function of the Exhaust Gas Recirculation Vacuum Regulator ( EGR VR) solenoid. The test fails when the EGR VR circuit voltage is either too high or too low when compared to the expected voltage range. The EGR system must be enabled for the test to be completed.

Why is my EGR VR solenoid not working?

What should I do if my vacuum regulator solenoid is defective?

Replacing the defective EGR control solenoid will likely correct your concern. To remove the EGR valve, you should first remove battery ground cable. Then, disconnect the EGR vacuum regulator valve. Next, disconnect the electrical connector, then disconnect the vacuum hoses.
