92 V6 Camery heat sensor

I assume you mean the coolant temperature gauge in the dash. The temperature sender is in the intake manifold, between the two cylinder heads, at the front of the engine (passenger side of engine compartment). It's connector is black plastic and has only one terminal.

I suggest you consider replacing the thermostat if it is stuck open. This is a much more likely cause, unless you find that someone just left the temp sender connector off during a previous repair.
