Cooling problem, fans on all the time

Hi guys, first timer here. Well, my problem is this, two days ago I changed the heater hoses. But when I removed the driver's side hose, the little tube that has both temp sensors broke, apparently it was corroded. So I went to the local junkyard and found one with only one sensor on it, (it was from a 2001, mine is a 99, but both were vulcans) I thought it was ok for the meantime. So I went on and put it in the car, connected only the connector for the temp sensor, not the sender. After installing everything back I tried to star the engine and it took a really long time, I even had to press the gas pedal like in a carburated car and it started very roughly, like if it had low gas pressure and then it settled in a nice idle, right in that moment the fans turned on and didn't stop until I turned off the car. It's been doing that on cold starts since then.

My question is, does the car need both sensor connected to operate properly? As far as I know, the sender is only for the temp gauge. To make it more clear, my tube has two bosses with one sensor in each, the tube I got from the junkyard has only one boss with a sensor in it

I thought that the sensor and sender as you call them screwed into the engine and not a hose. Can you post a picture of the senders or hose?

Seems pretty obvious to me that the PCM no longer has a temperature input and no way is the car gonna run right like that.

^^^^ Yup! No ECT input to the PCM will run the fans on high speed constantly.

^+1. Erick, you need the "twofer". If you can't find a good 1 at the jy, may try Rockauto online.

Thank you very much for your replies guys, that definitely points me in the right direction.

I will post some pictures tomorrow, but you can get the idea by searching "99 taurus water outlet tube" (finally found the name of that thing!) They have it on ebay, but I'm in Mexico, so 45 bucks is a lot for my economy ?

Can you use two of the fittings in series and that would be cheaper than a double fitting. Not sure of the room you have.

It's basically the same if I use two fittings, luckily I found one with the two holes in a jy in good shape, I bought both sensors and the car fired right up, the gauge is working and the fans turn on when they're supposed to. Thank you very much guys, you were very helpful.
