Hi, iam Joanne Freeman, Don’t work too hard.

How Much Resistance Should A Coolant Temp Sensor Have? [Solved]

In cold engine and an ambient temperature of 20 ºC the sensor resistance is between 2000Ω and 3000Ω. After the engine start, coolant temperature begins to rise. ECT gradually heats and its resistance reduces proportionately. At 90 ºC its resistance is in the range of 200Ω to 300Ω.
