0115 coolant temperature circuit malfunction

[503posdsm]

Im having some problem with the temperature sensor in the DSMLINK is reading -74, and im getting a check engine light. I already change the temp sensor but it still does the same, also change the temp switch just incase it was that but the code still coming up it read 0115 engine coolant temperature circuit malfunction. any help would be great

Did you change the 2 wire sensor, not the 1 wire one? If so check the connector and wires for poor connection, and then ECU.
