Question about 2002 Chrysler PT Cruiser
When unplugging the wire from the temp sensor you should have an open circuit. The temp sensor once it detects a high temperature, would create an open circuit and the fan should turn on. I would say that the temp sensor is good, also you mentioned that you have replaced it. This most likely is a wiring issue. The tricky part is locating the problem. You will have to trace the wire from the sensor towards the harness to identify any bad wires or open connections.

You don't have an open circuit, that is evident when you remove the wire and the lamp goes on.
Do you have an overheating problem or was your problem the temp gauge all along?
Buy a flush kit and flush the cooling system, it may be clogged
