The ECU has seen supply voltage outside its expected window. Almost always charging or battery related, and it can throw a scatter of unrelated codes alongside it.
P0560 — also written PO56O, P 0560, 0560 — is the OBD-II code for system voltage malfunction. Same code, same fix: this page covers every spelling of it.
P0560 is a electrical fault code, typically costing £80–£650 to put right in a UK garage.
What causes P0560?
- Failing battery losing capacity
- Alternator over- or under-charging
- Corroded battery terminals or earth strap
- Loose or worn alternator belt
How P0560 is fixed
- Load-test the battery and check charging voltage at idle and 2,000rpm
- Clean and remake terminals and earths
- Replace the alternator or regulator
- Fit a new battery if capacity is down
P0560 repair cost in the UK
Most P0560 repairs land between £80–£650 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
