Time to change your oil in your engine!
Add brake fluid
Evidently the oil level was low before you changed oil and was full thereafter.
The low coolant sensor is located in the side of the radiator. It can be unplugged but then how will you know it is low.
It requires a scanner to properly diagnosis a check engine light.
There is one screw that holds the fog light it into place.Unscrew that screw and the fog light will pull out of the bumper.
Well, the common cause for the light coming on is the radiator is low of coolant. But I assume you have checked the coolant level and it is ok. That being the case more than likely the coolant level sensor is defective and needs replacing. Can also be the problem is in the wiring.
As per the instructions on page 5-55 of your "Owner's Manual"...
