P0560 OBD-II Trouble Code: System Voltage Malfunction

P0560 code definition

The P0560 engine trouble code identifies a problem with abnormal voltage readings, coming from the battery, starting, or charging systems.

What the P0560 code means

The P0560 engine trouble code means the vehicle’s powertrain control module has detected an abnormal voltage reading. This reading comes from the battery, starting, or charging systems, and is deemed abnormal by your PCM for being higher or lower than expected.

What causes the P0560 code?

The P0560 code has a number of common causes, including:

  • Alternator failure
  • Battery failure
  • Starter or charging system failure
  • Faulty wiring
  • Faulty battery cables
  • Defective voltage regulator
  • Corroded battery terminal ends
  • Otherwise defective or malfunctioning vehicle battery

In rare cases, there may be a PCM failure that resulted in the P0560 trouble code being stored unnecessarily.

What are the symptoms of the P0560 code?

The P0560 code can be accompanied by many symptoms, including:

  • Illuminated check engine light
  • Illuminated battery light
  • Stalled engine upon vehicle idle
  • Issues with transmission shifting (with automatic models)
  • Decreased fuel efficiency

How does a mechanic diagnose the P0560 code?

After a full inspection, your qualified mechanic will use a OBD-II code reader to determine when and how the P0560 engine trouble code was logged into the vehicle’s PCM. Then, the mechanic will test your vehicle’s battery, check if it still functions and holds a charge, and perhaps replace if the battery is deemed the source of the issue.

They will also replace any worn or faulty cables, wiring, or connectors, and inspect the entire vehicle again to ensure their repairs were sufficient. If there are still any issues, your mechanic will look into the possibility of an issue with your vehicle’s PCM.

Common mistakes when diagnosing the P0560 code

Many mechanics report that they often see customers who have had their vehicle’s batteries or starting and charging systems unnecessarily replaced when the real source of the P0560 code was from an issue with the car’s alternator. This indicates that the vehicle’s alternator is having issues with charging, and this should be one of the first issues a qualified mechanic will inspect upon encountering this engine trouble code.

How serious is the P0560 code?

While the P0560 code on its own isn’t as concerning, any potential issues with the vehicle’s battery or charging systems can also negatively affect other systems in your vehicle, including:

  • Security and locking systems
  • Audio, telephone, and navigation systems
  • In-vehicle entertainment systems
  • Power seating systems
  • Climate control systems

Over time, the vehicle will also experience decreased fuel economy. Therefore, it’s always best to have your car inspected and diagnosed by a qualified mechanic if your PCM records the P0560 engine trouble code or if you experience any of this code’s symptoms.

What repairs can fix the P0560 code?

The most common repairs to address the P0560 code are as follows:

  • Battery replacement
  • Alternator replacement
  • Wiring, cable, and connector repair

Some vehicles may also be issues with the vehicle’s PCM or additional charging and starting system failures, which will require more complex repairs to these systems or full replacements.

Additional comments for consideration regarding the P0560 code

Be sure your vehicle is accurately inspected and diagnosed before committing to a part replacement, as the solution to the P0560 code is sometimes hard for technicians to discern. Once the necessary part has been replaced, ensure that your mechanic has performed continuity testing and an after-replacement inspection on all system circuits to confirm the replacement fixed the issue.
