2004 Chevrolet S10 Question: Map Sensor Code

I get a Map sensor code and i think it is from a vacuum line that goes into the valve cover on the passenger side. That rubber insert is a little loose. What is that part called? -

It is called the PCV grommett, but are you sure that is the problem? Are there any other vacuum leaks? And, GM Map Sensors do fail. -
