You need to give some more detail.
What year is your LS?
Which engine is your LS?
What was the exact five character OBDII code?

Yes, the LS has a MAP sensor, exactly where depends on the answers to the questions above.

The MAP sensor is inside the EGR valve assembly. Before you replace the EGR, look carefully at the little plastic hard-line vacuum lines that run to it. If any are cracked, that could be your problem. If they aren't cracked now, they probably will be when you remove the EGR valve (they get very brittle with age).

The vacuum hose assembly is 3W4Z-9E498-BA. It's just described as "connector."
The EGR valve assembly is 3W4Z-9D475-AC.

FordPartsGiant.com has them both for a little less than $150 with shipping. You may be able to find a better deal.
 
Thanks Joe I'll look at the plastic parts tomorrow..That sounds right cause I just replaced all my coolant plastic parts last summer..thanks
