What causes low system voltage?
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 code P0562 on a Dodge Journey?
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. Driving with this trouble code is not recommended.

If a problem or malfunction is detected, the OBD II system illuminates a warning light on the vehicle instrument panel to alert the driver.
Can a bad battery cause engine codes?
A dying, fading car battery means low voltage. As a result, your car’s computer, which is responsible for reporting error codes, is also receiving low voltage. An error code will be generated which will in turn trigger the Check Engine Light or even the Battery Charge Warning Light to display.
