tw sensor???

i have a sensor that broke and i found out that its the tw sensor in my helms manual but cant find anything else about it. what does it do??? it is located directly next to the coolant temp. gauge sender.

i know i should replace it but my car has so many problems i need to know what the job of this sensor is.

thx in advance, someone always comes through on here :smiley:

The TW sends info to the ECU which coordinates with the rest of the sensors to regulate engine timing and fuel to keep the car emissions within EPA guidelines:baby:
