The error code P2185 in a 2012 Honda Accord indicates a problem with the "Engine Coolant Temperature Sensor 2 Circuit High." So, 9 times out of 10 it will be the coolant sensor has shorted open and needs to be changed out. Here is the location of the sensor which is in the lower part of the radiator so you can get the problem fixed. Check out the images (below). Let us know if you need anything else.
