Outdoor temperature sensor open or short circuit

From Service Manual 326125, p.17:

1.Check if the outdoor temperature sensor connector is separated from PCB; measure resistance between both terminals and compare to temperature table.

2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).

3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
