That MAP sensor taps the manifold directly there is no vacuum hose for it.

Unbolt it and pull it up you will see the stem that goes thru to the manifold.

If you are having problems it could be the stem is clogged or the O ring has deteriorated

I told you pull the one off your car and you will see the vacuum source. Comes in the back of the sensor.

I know that there is a tip on the bottom of the senor what I can;t figure out is where does the hose off there hook to. When I took this sensoe off there was no hose at all. Is there supposed to be or doe's it just work electrical? I sure this one is no good because the back comes right off of the case. I appreciate you advise and I know you may have to talk to me like a 3rd grader but I what to make sure I have it plugged in right.
