It is a 2.2 liter


Hi James. So there are two wires that ground the electrical, the one that traces to the firewall is going to be your ground. For the MAP sensor itself, unless you rewired the harness, you shouldn't need to worry about this issue. The OBDII ECM in the car doesn't self assess. Meaning that it cannot reset it's own codes, you have to clear the codes once the problem has been fixed. I learned that on a 98 with an EGR valve issue. I would go ahead and reset the codes, if you have a ccde reader but before you do, save the Freeze Frame Data thats throwing the initial code. I hope this helps!
