Engine Coolant Temperature (ECT) Sensor Problem

[IB_STROKIN]

I replaced the Engine Coolant Temperature (ECT) Sensor on 2001 Excursion 7.3L PowerStroke and the factory temp gauge stays bottomed out at "C".
The sensor is new and it seems to work fine - at running temperature the new sensor reads 3.66Kohms. When engine is cool it reads somewhere around 8.0Kohms. Although I'm not convinced that it is necessary, I did take a jumper wire from the brass fitting on the sensor to the engine block - it did not help. Also, when I take the connector off of the sensor and apply a low resistance (100 Ohms) the temp gauge rises to just over normal running needle position. What can go wrong - thread in the sensor and plug the connector on right? Can anyone help?

Thanks

Hey man, I'm having the same problem with my truck I've been fighting with it for weeks. Have you solved your problem if so, please tell me what it was!!

Yes - I did get the issue resolved.
For me it was a wrong part from the store.
There were two or three sensors available, and initially I was given the wrong part.

The correct part number was WT763.
The brand/manufacturer was BWD.

When checking resistance across this sensor cold, it reads about 1500 Ohms - that is when held in hand.

I had the same type problem when I replaced it alonhg with the waterpump. Parts store "correct #" ect simply did not work-the dash gauge would not register. My solution, gleaned from the forums, was to get the dealership part. It was under ten bucks and solved the problem. Now if I can just chase down the dang belt/bearing noise....
