Code P0117 2000 Ford F150 Description

The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Powertrain Control Module (PCM). The modified signal returns to the PCM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. The Diagnostic Trouble Code (DTC) indicates the sensor signal is greater than the self-test maximum. The ECT sensor minimum is 0.2 volts or 121°C (250°F).
