My check engine light came on throwing a code 105 which is map/barometric pressure circuit malfunction. I ran through the tests but I cant figure it out because I dont know what the terminals are. The thing that puzzles me is all of the terminals have some kind of voltage its a 3 bar connector, the first wire (green) has 5.3v second (black) has.04v and third (white with red stripe) has.04v I checked for resistance in the plug and it shows none. I dont know where to look from there? I also changed the map sensor and reset the ECU but it threw the code again after driveing a few miles. Thank you I appreciate your help.
