P0514: Battery Temperature Sensor Circuit Range/Performance — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
Battery Temperature Sensor Circuit Range/Performance. Basic catalogue definition; diagnostic details have not yet been reviewed.
Affected system: Powertrain
Symptoms
- Warning light may illuminate
- System function may be impaired
- Symptoms depend on the vehicle and fault conditions
Possible causes
- Weak battery, charging fault, poor ground, sensor fault, or harness damage can cause voltage anomalies.
- Connector, wiring, ground, or supply-voltage fault
- Vehicle-specific mechanical or control problem
What to check
- Record codes and freeze-frame data
- Measure battery and charging voltage under load, compare with scan data, and inspect grounds, sensor wiring, and charging system.
- Compare results with vehicle-specific service information
- Verify the repair and monitor readiness
- Measure battery and charging voltage under load, compare with scan data, and inspect grounds, sensor wiring, and charging system.
- Repair the confirmed cause and retest under the original fault conditions
Also written as: P0514-00, P051400, PO514 (some scan tools add the fault-type byte, e.g. -00).
