2000 Mazda 626 Question: P0118 coolant temp code

Hi everyone! Can you tell me what this code means, where the sensor is located, and how it affects the running of the engine? I would appreciate any feedback I get. -
Answer 1
in most cases, this code is from a thermostat stuck open. the engine never heats up to the proper operating temp. i would check the temp when hot before replacing anything. Roy -
