2001 CHRYSLER VOYAGER ignition

Symptom:
AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT TO GROUND
When Monitored and Set Condition:
AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT TO GROUND
When Monitored: Whenever the Power Liftgate Module is awake.
Set Condition: If the module senses a resistance below 1000 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 (68É F) the resistance will be between 11.2 K and
13.5K ohms.
