check engine light

P0515 code definition

A P0515 Trouble Code indicates a problem with the battery temperature sensor circuit.

What the P0515 code means

The powertrain control module, or PCM, has found that the battery temperature sensor circuit has a voltage reading that is out of the normal range. Whenever the temperature readings for the battery are too high or too low, according to the tolerance level dictated by the manufacturer, the code will be stored.

What causes the P0515 code?

Let’s look at some of the most common causes of the P0515 code:

What are the symptoms of the P0515 code?

There are really no major symptoms with the P0515 code. The only things that will happen is that the trouble code will be stored and the Check Engine Light will be illuminated.

How does a mechanic diagnose the P0515 code?

When the mechanic is trying to diagnose the P0515 code, he or she will use their OBD-II scanner. They can attach this tool to the vehicle’s computer system to gather data, which can help them with the diagnosis and repair. They will also visually inspect the wires and the battery to see if there are any issues. The mechanic will want to reset the code as well and then drive the vehicle to see if the code comes back.

Common mistakes when diagnosing the P0515 code

When this code shows up, many believe that there is actually an issue with the battery. They replace the battery, but the code remains.

How serious is the P0515 code?

The code is not very serious at all. The only thing that you have to worry about is the illuminated Check Engine Light. However, that doesn’t mean that you should ignore the problem. The mechanics might find that there is too much corrosion on the battery that’s causing the problem. This could indicate that the battery is eventually going to fail. Always make sure you get your vehicle repaired properly.

What repairs can fix the P0515 code?

The following are some possible repairs that the mechanics will use to help fix the P0515 code. * The mechanic will look at the wires and connectors, as well as the battery to see if there is a problem. * They might try another battery, then reset the code to see if it comes back. * If the problem is truly the battery temperature sensors, they will replace them.

Additional comments for consideration regarding the P0515 code

Although the battery temperature sensors might not seem too important, and the presence of the code doesn’t necessarily mean that the vehicle is going to have issues, it’s a good idea to have it taken care of. Whenever you have anything, large or small, wrong with your vehicle, it is a good idea to bring it to a mechanic to have it repaired properly.
