A bad egr solenoid can cause a variety of different trouble codes so having the computer scanned for.

Egr vacuum regulator solenoid circuit malfunction.

An illuminated check engine light is another symptom of a bad or failing egr control solenoid. This test checks the electrical function of the exhaust gas recirculation vacuum regulator egrvr solenoid. An egr switch consists of a valve vacuum and solenoid. The test fails when the egrvr circuit voltage.

When a vehicle s combustion temperature rises above 2500 degrees the egr valve opens and the vacuum draws in exhaust to help balance out harmful emissions. The test fails when the egrvr circuit voltage is either too high or too low when compared to the expected voltage range. How to repair p1409 code egr vacuum regulator solenoid circuit malfunction. The test fails when the egrvr circuit voltage.

This test checks the electrical function of the exhaust gas recirculation vacuum regulator egrvr solenoid. If engine vacuum was present after the engine was started and was idling this indicates that the vacuum line is good and delivering the goods to the egr vacuum regulator solenoid. The egr system must be enabled for the test to be completed. If the computer detects an issue with the egr solenoid circuit or system it will set off the check engine light to notify the driver of the issue.
