P0562 — System Voltage Low

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0562

P0562 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0562 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0562 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0562 fault code is set when the Engine Control Module (ECM) detects that the system voltage in the vehicle is lower than the expected range. This code indicates a situation where the voltage in the vehicle's electrical system is not sufficient to properly operate the vehicle's electrical components, including the ECM and various sensors and actuators. Low system voltage can result in a range of issues, such as poor engine performance, electrical components malfunctioning, difficulties in starting the engine, and dimming of lights. Causes of low system voltage can include a weak or failing...
