Temp Gauge

[Mr_Calais]

hey guys i hav a temp gauge problem gauge on my dash. I have a digital dash and when i first got the car the gauge used to go between lowest temp marking to the hightest mark and then the car would beep at me letting me know. and this would happen all the time even tho the car was not over heating at all. but know the temp marking just stays at the lowest marking no matter how long i drive it for.
the only thing i have replaced is the coolent temp sensor on the side of the block. but no luck
ne ideas of what it could be or what could fix it( i hav the injected motor btw)

Thanks
