Code P0117 Lincoln Description
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. The voltage that is dropped across a fixed resistor (pull-up resister) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT Sensor is located in an engine coolant passage and measures the engine coolant temperature. The PCM uses the engine coolant temperature input for fuel control and for cooling fan control. The ECT Sensor can be a threaded or twist lock type.
This Diagnostic Trouble Code (DTC) is set when the ECT Sensor signal is less than the self-test minimum. The ECT Sensor signal minimum is 121°C (250°F).
What are the Possible Causes of the DTC P0117 Lincoln?
- Low engine coolant level
- Faulty Engine Coolant Temperature (ECT) Sensor
- Faulty engine coolant thermostat
- Engine Coolant Temperature Sensor harness is open or shorted
- Engine Coolant Temperature Sensor circuit poor electrical connection
