2001 S60 2.4T. Only recently has the radiator cooling fan continued to run for a while after I shut off the car. Temp gauge is indicating normal when I drive. The only thing changed recently is that the wiring to my fuel injection system was repaired due to being chewed up by squirrels. Fluid levels are good. Is there a potential issue with engine cooing?

thanks

 

Bad temp sensor will cause that.
