Hi so I bought a 2005 Chevy Cobalt SS and one of the codes that I'm getting the one I can't get to go away is the p2229 and I've replaced the map sensor that is on the Eaton supercharger but there's what appears to be another map sensor that has an electrical connector and a nipple on the bottom but nothing connects to it and when I unplug it I get a p2228 code so I'm not sure exactly what it is is it an extra map sensor is it the barometric pressure sensor ambient sensor or whatever it is you know I can't find a replacement for it because everything says that the barometric sensor is in the map sensor but this sensor is there any help would be appreciated
