Code P014, Shorted ECT Sensor Signal: Notes

Engine Coolant Temperature (ECT) sensor is located on thermostat housing. ECT sensor signal is on circuit No. 410. Sensor ground is on circuit No. 808. As sensor temperature increases, resistance decreases. A high coolant temperature will result in low signal voltage on circuit No. 410. Code P014 sets because engine coolant temperature cannot be greater than 296°F (147°C) when intake air temperature is less than 212°F (100°C).
