PO 116 This is a temp sensor code that sets when the PCM detects that the temperature difference between the engine coolant temperature and the intake air temperature, after a specific time with the engine off, is not within the calibrated range after the ignition off time.

Check coolant levels
Let engine set for 10 hours (to get ambient temps on both sensors)
Reset/clear all codes.
Restart engine and monitor codes.

I suppose it could be the intake sensor going bad too.
