Symptom:
P0516-BATTERY TEMPERATURE SENSOR LOW
When Monitored and Set Condition:
P0516-BATTERY TEMPERATURE SENSOR LOW
When Monitored: Ignition on.
Set Condition: Battery temperature sensor voltage below 0.5 of a volt.
POSSIBLE CAUSES
BATTERY TEMP SENSOR VOLTAGE BELOW 0.5 VOLTS
BATTERY TEMP SENSOR INTERNAL FAILURE
BATTERY TEMP SIGNAL SHORTED TO GROUND
BATTERY TEMP SIGNAL SHORTED TO SENSOR GROUND CIRCUIT
PCM
TEST ACTION APPLICABILITY
1 Ignition on, engine not running.
With the DRBIIIt, read the Battery Temp Sensor voltage.
Is the voltage below 0.5 volt?
All
Yes → Go To 2
No → Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
2 Turn the ignition off.
Disconnect the Battery Temp Sensor harness connector.
Ignition on, engine not running.
With the DRBIIIt, read Battery Temp Sensor voltage.
Does the Battery Temp Sensor voltage read approximately 5.0 volts?
All
Yes → Replace the Battery Temperature Sensor.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 3
3 Turn the ignition off.
Disconnect the Battery Temp Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the Battery Temp Signal circuit in the
Battery Temp Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the Battery Temp Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 4
