It might not be the sensor (PN# 65818350779), but the wire connecting to it. That was the case with mine. Cost me 3 bucks for the new wires with connectors from the dealership.
picture for reference:
This is located in your drivers side brake duct located beside your fog light. It clips into the duct. Pull it out, and the sensor should be on a slide-lock, so you can just push on the lock and release the temp sensor from the housing. There should be 2 wires running into the housing. Mine were green and corroded. I went to the dealer and asked for the wires that ran to the temperature sensor, and they provided them to me.
10 minutes later, i spliced the new wires into the yellow box and the temp reads fine again.
