My guess is that the thermostat is broken. Replace it with a new one and everything will be back to normal. I assume you have checked the coolant system and refilled it so it don't runs dry? Visit your nearest Honda dealer and get a genuine radiator cap.

Welcome to the forum BTW! :D

WHEN THE ENGINE IS COLD (!!!) remove the cooling system cap and look for any obvious signs that the cap or seal is damaged. Do also check that the coolant level is correct.

A faulty thermostat would either result in a longer warm up than normal if stuck open, or over-heating if stuck closed (which would be indicated as a higher-than-usual temperature on the gauge).
