Code P01F0 2016 GMC Sierra Description

The Engine Coolant Temperature (ECT) Sensor is a 2-wire negative temperature coefficient thermistor. As the temperature of the fluid increases, the resistance of the sensor decreases, varying the voltage on the signal circuit. The Engine Control Module (ECM) uses this diagnostic to determine that the Engine Coolant Temperature (ECT) does not fall below a minimum calibrated temperature after the vehicle has reached normal operating condition. The Diagnostic Trouble Code (DTC) will be set if the Engine Coolant Temperature is less than 71°C (160°F) for greater than 30 s.
