Code result
P0514
Battery Temperature Sensor Circuit Range or Performance
Moderate severity
What it means
The battery temperature sensor reports a value within plausible range yet inconsistent with engine bay or coolant temperature. Modern alternator regulation uses battery temperature to adjust charging voltage, so an offset here causes over- or undercharging.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
