Have a P0117 fault code at 82K. This is a low input Engine coolant temp fault. Changed timing belt, serpintene belt,water pump and flushed coolant system at 80K. Engine temp not running hot. No performance issues and check engine light on but not flashing. Is this a coolant flowing problem? Need to know where the sensor is to change it?

the code is for temp not reaching normal operating temp. as i said before, you need to start with a thermostat, which you did not list in your parts replacements.
