Question about 1999 Ford Explorer
Code 117 is either the Engine coolant temp sensor or the cylinder head temp sensor depending on which application you have.
Indicates the sensor signal is less than Self-Test minimum. The ECT sensor minimum is 0.2 volts or 121°C (250°F).
Do you have access to a scan tool that can read PIDS? If so access the PID and see what it is reading,then disconnect the sensor and see if the voltage then goes to over 4V.If so replace the sensor, if not make sure the wires going to the sensor are not grounded out somewhere.

Have you checked your filters ?? air, mass meter, any hose burnt , cracked, ??
also there is a throttle position sensor that is in charge of opening and closing the intake, if thats faulty it will cause this problem too.
