Water temp resistance
#2
Readings depends on water temp. You're supposed to pull the sensor and put it water, then slowly heat it up while taking temperature and kohm measurements. I suppose you could leave it in, and use your OBDII reader/diagnostic tool to determine the coolant temperature and perform the same tests.
Degrees(F)___ kohms
14___________7-11.4
68___________2.1-2.9
122__________0.68-1.0
194__________0.236-0.26

See the Factory Service Manual, Section EC, page 145 (Link is in my signature, use it!!)

That depends on the temperature of the coolant .
it would be about right if you are testing the ohms first thing in the morning if the temperature is in the low 60s.
also test it after the car is at operating temperature. That would be the 194 degree ohms on the chart
The Wizard sent you.
one of the best methods involves removing the sender. Plug the hole with wadded up paper towel. It won't leak much.
Put it in your freezer. Expect ohms higher than 11.4
then use alligator clips between the contacts on the sensor and the ohm meter leads. Put some water in a pan. Put that on the stove. Turn the burner on.
use a cooking thermometer to compare the water temperature against the ohms chart. Should compare fairly closely.
Sometimes the sensor has the right ohms at cool temps, but not at higher temps. If that happens, the computer will believe that the car is cold.
or the opposite. The computer can only react properly to accurate information.

yes it was but I change it out .. and put a new oem crank sensor ... clean up the ground were it meets to trans because of the oil leak ..now my code is gone for P1335.. she starts strong on the first crack so far ...I made sure the sensor was oem ... I was thinking of adding a ground wire from neg terminal to the strut bolt will it make a difference and using 16 gauge wire ?

I could see adding another ground if the transmission has been out of the car, or if the main ground cable has corroded.
If I were to bother adding a ground, I would use something larger than #16 wire. I would use at least a #12 wire, or a #10. You can buy wire by the foot at a good hardware store or a Home Depot or similar.
