These were originally hard soldered or welded from the factory, not sure,  
it's impossible to melt the connection with a soldering iron though. The crux of 
 a good connection here is strain relief, normal solder will wick up the wire 
and  make it brittle, it will then be prone to breaking again. Some advocate 
the  putting crimps on the wire then soldering the crimp to the sensor.
I soldered mine back on and then tie wrapped the wire back to the body of  
the sensor leaving a small loop of wire, you could also use a P clip and bolt it 
 to the sensor mounting bolt.
My connection has lasted about 18 yrs like this. I still have the spare  
sensor I bought at the time..
