New Egr Valve Vacuum Leak at Jose Shepherd blog

New Egr Valve Vacuum Leak. If the vacuum diaphragm inside the egr valve is leaking, the vacuum will drop. Find the solenoid in your engine bay, usually near the egr valve. If there is a fault in the egr system, it can cause the egr not to function properly. Vacuum lines and the control solenoid must. Locate the egr vacuum solenoid: Apply vacuum directly to the egr valve using either a hand vacuum pump or scan tool depending on the type of egr valve. If egr is commanded but the pcm sees no egr flow, one possible cause is the egr vacuum regulator (egr modulator). If there is no change in idle quality, then either the egr valve is faulty. Once the vacuum is released, the valve should close fully. If the egr vacuum modulator diaphragm tears or leaks it will. One of the first problems of a potential issue with the egr vacuum modulator is engine performance issues. If an egr valve is stuck open, it creates a vacuum leak, with the only difference being that instead of air, it's the exhaust gases that enter the intake manifold.
