How many coolant sensors?

How many coolant sensors are on my engine? There is one on the front of the thermostat housing with one wire coming out. Then there is another on a few inches away on top right beside the thermostat housing with two wires coming out of it. Anyway my truck is running like crap and the sensor on the top is broken in half. Can you tell me what that sensor is or what it controls? I am hoping this is why its running so bad. thanks.

u have technically 2! the one with "1 wire" is the temp gauge sensor for ur cluster temp gauge, and the one basically right ontop/ in ur water pump is ur actual "ECT" sensor

so i'm thinking you would want to replace the one with 2 wires. as that actually affects what the computer sees.
