DTC P1409: EXHAUST GAS RECIRCULATION (EGR) VACUUM REGULATOR SOLENOID CIRCUIT

Description:	This test checks the electrical function of the EGR vacuum regulator solenoid. The test fails when the EVR 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:	EVR circuit open EVR circuit short to voltage EVR circuit short to ground VPWR circuit open to EGR vacuum regulator solenoid Damaged EGR vacuum regulator solenoid
Diagnostic Aids:	The EGR vacuum regulator solenoid resistance is between 26 and 40 ohms.
