I am trying to find the test range on this sensor. A cold test after sitting all night is 55,300 ohms . coolant temp is 56*F . air temp 46* F

After driving the truck 10-12 miles
29,250 ohms . coolant temp is 133*F air temp 46* F

Truck had 170k when i bought it , now 250k . Don't know if it had ever been replaced prior .

Thank you
