Looking for answers. Getting code P0117 and P1000

What is your question?

Had to replace compressor for a/c, the 02 compressor because check engine light came on and failed inspection, then passed inspection. Then all lights and gauges showed engine overheating, check engine light on, so thought it was the thermostat but took to Auto Zone and ran diagnostic check temperature sensor reading was at 104. Engine block reading temperature was 179 to 185. Diagnostics Codes show P0117 and P1000 and P1647. Thinking that temperature sensor is bad and it is not letting the fans turn on? NEED HELP PLEASE. Car has 64,000 miles only and mint condition. Need to fix ASAP. Thanks!
