When I worked for an automotive OEM several years ago, we would put just
a drop or two of some magical superglue-type stuff from Locktite in the
connector area of coolant sensors to prevent exactly this from happening.
Sorry, never did know exactly the name or composition of the stuff, just
that it was an isocyanurate (sp?) of some kind, so I suspect retail
superglue will do the same job. It was very thin to flow down into the
minute spaces between the metal conductor and plastic insulator. Once it
set in a minute or two, we tested them up to 120 psi without any
failures. You might want to try superglue as a field expediant to get
back on the road in a hurry.
