Ambient Temperature Sensor Circuit Short To Ground - Chrysler Town and Country 2003 Owner's Manual

POWER DOORS - LIFTGATE
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 (68° F) the resistance will be between 11.2 K and
13.5K ohms.

TEST
1 With the DRBIII , record and erase DTC's.
Turn the ignition off, wait 10 seconds, then turn the ignition on.
Operate the liftgate several times.
With the DRBIII , read DTCs.
Does the DRBIII display AMBIENT TEMPERATURE SENSOR CIRCUIT SHORT
TO GROUND?
Yes → Go To 2
→ Using the wiring diagram/schematic as a guide, inspect the
No
2 Remove the power liftgate motor trim panel.
Disconnect the Power Liftgate Module C2 connector.
Measure the resistance between ground and the liftgate Temperature Sensor Signal
circuit.
Is the resistance below 5000.0 ohms?
Yes → Repair the Liftgate Temperature Sensor Signal circuit for a short
→ Go To 3
No
