If you unplug the sensor will the gauge drop all the way down?Any codes in the computer?

I think it might have been a defective ECTS because I bought another one at a different merchant and now it reads at it should but my fan is still not working

There is a seperate sensor for the fan operation.

It is right below the throttle body on your vehicle.
