Is there such a thing as an IMAP sensor? What is it? on 1993 Saturn SL1

I had a check engine light diagnostic done on my Saturn and the low coolant sensor came on (it wasnt low) and the imap sensor. It was explained to me that this regulates air flow to the engine. Could be computer issues too, He wants $200. sound fair?
