P1409 EGR Vacuum Regulator Solenoid Circuit Malfunction Detailed Description
This test checks the electrical function of the EGRVR solenoid. The test fails when the EGRVR 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.

Possible causes :-
EGRVR circuit open.
VPWR open to EGRVR solenoid.
EGRVR circuit short to VPWR or GND.
Damaged EGRVR solenoid.
Damaged PCM.


Diagnostic Aids
