03 escape - low oil pressure light stuck on after replacing sensor.

[Kawana]

I replaced the low oil pressure sensor on my 03 escape 3L v6. Before replacement the light would flicker at low idle after the car was warmed up, and would shut off while accelerating. I replaced the sensor, and after starting it up, the light remains on at all times. Do I need to reset the computer or something? I cant think what I did wrong, it was a pretty simple procedure...
