coolant temp problem
alright guys i got a problem on my truck i bypassed a while ago and now i want to fix it. with a brand new temp sensor in the truck at about 160* or any warmer than that, it shows on the dash its at like 260 tached out and the check gauges light is on. i put a mechanical gauge in it and it it wrks fine and runs fine, but i would rather use the sensor on my dash. anyone know what would cause the gauge on the cluster to be bad?

dodges uses a hot and cold not numbers. and i know the sensor works. ive ohmed it out at like 10 different water temps and it works perfect. and when i send the ohm load to the cluster it goes wacky. i dont know if this is right im just using it as an example:
say 5 ohms is cold like truck is off (160*) and 50 ohms is as hot as it gets (260*). when i give it 7 ohms it shows like 200* and if i were to give it 15 ohms it gives it 260* degrees. it seems like the thermo resistor or something is bad but i dont know where it is or how to test it
