What the P0514 code means

The P0514 code indicates that there is a malfunction in the battery temperature sensor.

What causes the P0514 code?

There may be one or more causes for the P0514 code. One may be a faulty battery temperature sensor. Another cause might be that the battery temperature sensor harness is shorted or open. It could also be that your battery temperature sensor circuit has a poor electrical connection. You will need to investigate the problem thoroughly in order to determine just what is the particular cause. Run through tests on your own, or take your vehicle to a professional technician.

What are the symptoms of the P0514 code?

Symptoms for the P0514 code include an overheating engine and an engine light that will not turn off.

How does a mechanic diagnose the P0514 code?

A professional technician will use an OBD-II scanner and a digital volt/ohmmeter to perform a diagnosis.

They may begin with a visual inspection of your connectors and wiring. Your Powertrain Control Module (PCM) uses your battery temperature sensor input data to regulate the rate at which the alternator uses your battery. Usually a 5-volt reference signal is sent to the battery temperature sensor from the PCM, and this signal voltage is grounded through your vehicle’s sensor return circuit. Your vehicle’s PCM uses battery temperature for evaporative emissions component activation and to activate its heated oxygen sensor operation. Make sure that you replace or repair any damaged, shorted, disconnected, or corroded wiring, connectors, and other components. After the repairs are complete, make sure to retest the system to make sure that you were successful. If everything seems to be working well, connect your code reader or scanner to the diagnostic connector to record your freeze frame data and stored codes.

If all of your electrical circuitry appears to be working well, test for a system voltage signal along with a ground signal at the battery temperature sensor. In some cases, a P0514 can be difficult to diagnose, and as a result, you may have to allow the problem to worsen before you can determine exactly what the issue is. At times it can be an intermittent malfunction, which is more difficult to diagnose. If you run through these steps and still cannot locate the problem, disconnect your PCM connector and perform a continuity test on all circuits that are related to your battery. You might be tempted to diagnose your problem as PCM failure, but this is very rarely the issue.

Common mistakes when diagnosing the P0514 code

Many times you may see this code and think that you need to replace your battery. But this will not solve the problem.

How serious is the P0514 code?

The P0514 code is very serious and, unless you are very skilled and have the proper tools, should be looked at by a professional technician. If you do not attend to this problem immediately, it may your affect engine performance and could reduce your gas mileage. It could also damage other components on your vehicle.

What repairs can fix the P0514 code?

If you receive a P0514 code, you will probably need to replace your battery temperature sensor. In order to be sure, you will need to test the resistance of the battery temperature sensor and compare your findings with the manufacturer’s specifications. If your data does not match up with the manufacturer’s specified reference voltage, you know that you need to replace the battery temperature sensor.

Additional comments for consideration regarding the P0514 code

Many older vehicles have sensor problems that occur due to prolonged stress on the drivetrain. A P0514 can be very difficult to diagnose and repair. Your best bet may be to get your car into a technician who has the tools to diagnose your problem more accurately and in less time.

Rigoberto came on time & quickly diagnosed the problem- rats chewed thru wiring near the battery. He wasn’t able to fix it himself bc of parts, but gave me recommendations on where to go & how to not have the dealership sell me services that are not needed.
