Code definition P0562

P0562 is set when the PCM (Powertrain Control Module) detects that the voltage on the vehicle is lower than required. If the voltage level in the vehicle drops below 10.0 volts for 60 seconds or more while idling, the PCM will save the code.

What does the code P0562 mean

The vehicle charging system works to maintain a normal voltage level in the vehicle, typically in the range of 14.1 to 14.4 volts DC at idle with the headlamps off. If for any reason the PCM detects that the voltage level in the vehicle is too low, code P0562 will be set and the MIL (Malfunction Indicator Lamp) or the Check Engine light will illuminate.

What causes the code P0562?

A variety of problems can occur causing the vehicle voltage to drop and the P0562 code setting, including:

  • One or more masses of the charging system.
  • Faulty alternator
  • Battery deeply discharged
  • Defective voltage regulator
  • Faulty wiring or connector (s) to the alternator
  • Faulty wiring connecting the alternator to the PCM
  • Damaged B + battery cable from alternator to battery
  • Damaged battery and / or battery cables
  • Damaged PCM (rarely)

What are the symptoms of the P0562 code?

There are some notable symptoms that come with the P0562 code that is stored. Belong to them:

  • The Check Engine Light or MIL comes on.
  • Battery backlight
  • Unable to change gears
  • Reduced fuel efficiency
  • Shutdown at idle

Most of these symptoms could be related to other codes and other problems with the vehicle. If the engine shuts down at idle speed and refuses to restart, it can be assumed that the battery is the culprit. However, there are many problems that may be in working with the P0562 code, so it is important to have a professional mechanic diagnose the cause of the problem.

How can a mechanic diagnose the P0562 code?

By using an OBD-II scanner, the mechanic will first know if there are any other stored codes that relate to the charging system. Then they methodically work out the possible causes of the saved code. If a problem is found, such as bad grounding of the charging system, they will fix it, erase the code, and retest it to make sure they found and fixed the problem.

The most common errors when diagnosing the P0562 code

The most common mistake with P0562 is hasty, misdiagnosed. It is often assumed that the problem is a defective or dead battery, or a problem with the starter motor. Replacing any of them will not prevent the code from being saved and will not solve the blackout problems and other symptoms.

How serious is the P0562 code?

If the voltage level in the vehicle drops too low, the vehicle may become stuck in idle and cannot be restarted. For this reason, it’s important to fix the problem immediately to keep yourself and others safe while you’re on the road.

What repairs can remove the P0562 code?

Some of the most common fixes for code P0562:

  1. Repair or replacement of any defective, loose or otherwise weak bases in the charging system.
  2. Replacing a damaged alternator
  3. Replace damaged battery and / or battery cables, including battery B + cable
  4. Replacement or repair of a damaged voltage regulator
  5. Find and replace damaged cables or connectors on the alternator
  6. Replace or repair damaged PCM

Additional notes regarding the P0562 code

In some rare cases, the P0562 code shows no symptoms other than the Check Engine light being on. In this case, the problem should be dealt with immediately as it can become symptomatic and lead us to a stall. In addition, to pass the OBD-II Emissions Test, make sure that all codes have been cleared and that the Check Engine light is off.
