This high temperature on the sensor contacts will carbonize the residue oil left and degrade the electrical connection. I have some deoxit and I am going to measure the connection resistance of some 20 year old connectors before and after deoxit. I will report my measurements. I have a 4 wire ohmeter and I can measure easily to a milliohm (.001 ohm). Be back in a little bit.
