2000 Mazda 626 Question: P0118 coolant temp code



Visitor, 2.5L V6, Saint Paul, MN, November 22, 2010, 18:28

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.

    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.
