Does anyone know what the resistance numbers are supposed to be for the coolant sensor? I wana put a meter up to it because my car is stuck in a pre-programmed loop mode and ive replaced my oxygen sensor and spark plugs. Im now led to believe its my coolant sensor. Yes the temperature is displayed on my dash fine, but I have a feeling the ecu is reading the coolant temp incorrectly. Any help would be appreciated, I have no control of my fuel in WOT mode beause of this.

For the Beta1:
Coolant Temperature Sensor
Heat the sensor by submerging it in hot engine coolant.
Check that the resistance is within the specified range.
Resistance:
2.27-2.73 KΩ at 20°C (68°F)
290-354 Ω at 80°C (176°F)
The Beta2 should be around the same values
