Not sure if you have a typo, but the resistance decreases at temp increases on the sensor. Therefore if you have a short to ground in the wiring, the ECU will read that the engine is hot, and lean the mixture. As you noticed, disconnecting the sensor, and therefore having a high resistance, would simulate a cold engine signal from the sensor.
