Symptom:

AMBIENT TEMPERATURE SENSOR CIRCUIT OPEN

When Monitored and Set Condition:

AMBIENT TEMPERATURE SENSOR CIRCUIT OPEN

When Monitored:

Whenever the Power Liftgate Module is awake.

Set Condition:

If the module senses a resistance above 382K ohms on the Liftgate

Temperature Sensor Signal circuit, this code will set. The normal range for the sensor is
1.2K to 382K ohms. At room temperature (68° F) the resistance will be between 11.2 K and
13.5K ohms.
