possibly forgot to plug it back in.
sometimes the pins get loose in the connector itself...you can use a small pick to fix it..
if that doesnt fix it, check for continuity in the wires going to the sensor. if the connector is getting power to it, i would try swapping yours out with one of your buddies...if that doesnt work then i would suggest checking the lines for kinks or breakage..
