EGR VALVE

I just cleaned my EGR valves. I am still getting vacuum pressure in my engine. The air coming in is not a problem. Does my car has more than two EGR Valves? I did clear the codes.

There is only one EGR. I'm not sure I understand what you are saying. The intake system should have vacuum.

The hose to my EGR Pressure Sensor (HI) keeps popping off. What is causing that? Do I have a DPFE or a PFE system? What do I need to do to repair this problem?

If it suppose to have vacuum. Why is the hose popping off?
