About P0560

P0560 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.

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 P0560 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 P0560 fault code is set when the Engine Control Module (ECM) detects a malfunction in the vehicle's electrical power supply system, specifically related to system voltage. This code indicates that there are issues with the vehicle's electrical system voltage, which could be either too high or too low, or exhibiting fluctuations outside the normal operating range. The system voltage is crucial for the proper operation of the vehicle's electrical components, including the ECM and various sensors. A malfunction in the system voltage can lead to a range of issues, such as erratic sensor readin...
