Diagnostic trouble code P0562 is a common code with several possible causes, ranging from a faulty relay to a faulty alternator.
In this guide, you will learn about what the P0562 code means, what causes it, and how to repair it.
What Does the P0562 Code Mean?
Diagnostic trouble code (DTC) P0562 stands for “System Voltage Low.” If your vehicle has this problem, you will likely see the check engine light come on, or experience some other symptoms caused by the low system voltage.
The battery provides the main power source for most of the vehicle’s systems, including the engine control module. If there is a problem with this supply of power, it will affect the performance of the engine and other major components as well.
Symptoms of a P0562 Fault Code
In most instances, you are likely to notice several symptoms when your vehicle has been affected by a P0562 fault code. The first thing that you will notice is that your vehicle is not starting up properly. This can be caused by a low battery charge or a faulty alternator.
Another symptom that you are likely to notice is the illumination of a check engine light on your dashboard. You may also notice that your headlights are dimmer than usual, particularly at night. This can cause a serious safety concern, which is why it’s important to have your vehicle inspected as soon as possible if you encounter any of these issues.
Causes for a P0562 Fault Code
There are several different causes for this fault code, but in most instances, it is triggered due to an issue with the charging system in your vehicle. When it comes to this issue, there are only two main components that can cause problems: the alternator and the battery itself.
What is the Meaning of P0562?
The trouble code P0562 is thrown when the battery voltage input to the Engine Control Module (ECM) drops below normal. This can happen due to a variety of different reasons, but typically occurs when the battery is running low on power, or if there is a loose connection at the battery.
What are the Symptoms of Code P0562?
When you get a P0562 trouble code, it’s likely that your vehicle will not start, or will stall while driving. Once this happens, take note of how many times you were able to start and run your vehicle before stalling. This will help with proper diagnosis.
What are some causes of Code P0562?
As mentioned above, P0562 is usually caused by a loose connection in your battery terminals. In order to get this fixed, you will need to first identify which battery terminal is causing the issue. You can use a multimeter to test for voltage drop between the positive and negative terminals and find out which side has lost power. After finding out which side is causing problems, take off that terminal and look for any signs of wear or tear that may be causing the loose connection. The most common culprit here would be corrosion
Heres a list of the most common symptoms associated with a P0562 OBD code:
- Difficulty starting the vehicle
- The vehicle doesnt start at all
- General lack of power
If your car is experiencing any of these symptoms, it is highly recommended that you bring it in for a professional inspection.
A P0562 trouble code refers to a voltage drop between the battery and the alternator, which means that your car’s computer has detected a problem with the charging system.
This is a fairly common issue in older vehicles and can cause a number of symptoms, including:
- Difficulty starting the vehicle
- Engine misfiring
The most common cause of this code is a defective alternator. However, it could also be caused by faulty wiring or a bad fuse. To determine the exact cause, you’ll need to run some tests.
The P0562 Code is a standard diagnostic trouble code that detects an abnormality in the powertrain control module (PCM).
The PCM is a vehicle component that automatically regulates the engine.
The PCM receives and stores information about the operating conditions of the engine to maintain appropriate engine performance.
