Outside air temp sensor
The ambient air temp sensor is supposed to sit in a hole in the left side fog light grill. It clicks into a tube and the nose of it actually pokes out into the oncoming air.
Mine had fallen out, probably from scrubbing. I removed the 3 screws on the grill from the front, put the sensor back in and taped it securely. Reinstalled the grill. All fixed.
Random temps resulted from sensor falling out and sitting inside the air dam/engine bay.
