Fox Should there be a vacuum hose here? MAP sensor.

I kept getting a code 22 last summer for the MAP sensor out of range. I read up a little more about it and looked at it today and realized there is no vacuum hose connected to it, is that normal? I'm assuming it needs the hose but why wouldn't the previous owner put it on.

And if it does need a hose, does it connect here?

Thank you!

That is a egr coolent connection, the nipple on the other side gets connected to a nipple on the intake

So both sides are capped off, are either of them neccessary? And also where does the MAP sensor get connected to?

They are not necessary if your emissions stuff is gone, if you get inspections and your emissions stuff is functional then yes you need it, I would inspect it for leaks before hooking it back up.
this will help with the vacuum thinghttp://www.veryuseful.com/mustang/tech/engine/images/88Stang5.0Vacuum.gif

Ok thanks. I dont have any emissions equipment anymore. Still a little confused on the MAP sensor though

Your 1993 doesn't have a MAP, it has a BAP. It meaures atmospheric pressure. Located dead center on top firewall, no vac line hooked to the port.

Oh so maybe it's just a faulty BAP than. I'll have to go through the troubleshooting i saw in another thread. What's the point of the vac line input on the sensor if it's not necessary?

No hoses go on there. Barometric stuff.

SAme sensor was used on the 86-88 speed density mustangs. The vac line went to manifold pressure. In 1989 when ford went mass air, it changed to measuring atmosphereic pressure. Just left the original design in place

I think there was a little foam cap that the factory stuck on there but they don't last long
