Code P014, Shorted ECT Sensor Signal: Notes
Engine coolant temperature sensor is located on thermostat housing. ECT 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).
