Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
AS for the first code, i would check the wiring connector on the engine coolant temperature sensor.
I would next check the engine control module connectors, make sure you have tight and clean contacts, and no signs of corrosion or water ingress, as the module is located in the plenum chamber (under the windshield, in engine bay, remove cover for access, make sure the drain holes in this plenum chamber are not obstructed, and that water can drain rapidly, clean as necessary).
I would check the connectors in plenum chamber, as the other problems might have a common cause (short to ground on different circuits).
Start with these, and any connectors in engine bay that look loose, or with signs of water, or even dodgy wiring.
Then clear the codes, test the vehicle, check for remaining fault codes after that, and we'll proceed as necessary.
