P014 = Shorted engine coolant temp sensor. which is located behind the distributor on the thermostat housing and has a YELLOW and a BLACK wire attached to it.
P073 = Intermittent engine coolant temp sensor.
Replace the coolant sensor in P014, CLEAR (erase) the 2 codes from the computer and see if any codes return.
