Condenser thermistor open circuit

From Service Manual 911414, p.26:

1.Access service mode to confirm the active fault code and read stored error history.

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

3.Check the sensor harness for opens. A reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
