The P0562 code is stored when the PCM (powertrain control module) detects a vehicle voltage that is lower than requested. If the vehicle voltage level dips below 10.0 volts for 60 seconds or more while at idle, the PCM will store the code.
What causes code P0562?
In most cases, the P0562 code is going to result from a failing alternator. Other causes can include a bad positive battery cable, bad wiring or connection at the alternator, bad voltage regulator (on vehicles that still have a separate regulator), failing PCM or a dead-short parasitic battery drain.
What is P0562 system voltage low?
When the code P0562 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing a lower than requested vehicle voltage. The code will set when the voltage level goes below 10.0 volts for more than 60 seconds while the engine is running.
What does charging system voltage low mean?
This diagnostic trouble code (DTC) indicates that the powertrain control module (PCM) has detected that the charging system is no longer producing the correct voltage to sufficiently charge the battery.
What does the code P0562 mean on a Dodge Journey?
low system voltage
Code P0562 relates to low system voltage as you know. This may happen for a number of reasons such as a poor electrical connection, high resistance in the battery cable between the alternator and the battery or in many cases a faulty alternator.
How do you fix code P0562?
What repairs can fix the P0562 code?
- Repairing or replacing any faulty, loose, or otherwise poor charging system grounds.
- Replacing a bad alternator.
- Replacing a bad battery and/or battery cables, including the B+ battery cable.
- Replacing or repairing a defective voltage regulator.
How do you fix low voltage in a car?
There are several ways to fix low voltage on a car battery, including:
- Jumpstarting the battery.
- Taking the battery out and charging it.
- Replacing your alternator.
- Replacing the battery.
Can a low battery make your engine light come on?
A bad battery can cause problems in electrical and electronic parts, including the computer. It can even cause a “Check Engine” light. Next, test the alternator and pay close attention to the condition of its diodes.
Does a faulty alternator throw a code?
Will A Failing Alternator Throw A Code? It is highly likely that you have a failing alternator if you find code P0562. Make sure it is checked out before it fails completely. Check the belt condition if you suspect that the alternator is failing, even if there is no warning light.
