P0560 code meaning
System Voltage
What P0560 means
The module measures its own supply voltage. CARB allows other monitors to be suspended below 11 V, and above a maker's threshold only if the voltage itself is diagnosed – that is what these codes record. GM's engine modules and Ford's PCM set them without warning lamp. P0560 is the general code without low/high split, used differently: Saab's 2002 9-5 transmission module sets it below 9 V or above 18 V for 1 s and goes into limp mode; Saab's EDC16 diesel only above 17 V (24 V charger or jump start); the GM-built 9-4X as a low-voltage code. GM's and Ford's engine modules use P0562/P0563 instead.
P0560 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0560
- Charge warning
- Transmission limp mode (Saab)
- Several modules report codes, starting problems
Common causes of P0560
- Most likelyBattery weak or faulty
- Most likelyAlternator or regulator (under- or overcharging)
- PossibleJump start or charger at 24 V
- PossibleCorroded or loose battery terminals or ground strap
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0560 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 60 | The exact fault in that area. |
What to do next
- Note P0560 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0560
What does P0560 mean?
P0560 means "System Voltage". The module measures its own supply voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P0560?
Drive gently and only to a workshop. With P0560 the car can go into limp mode (reduced power) to protect itself.
Will P0560 fail an emissions test?
P0560 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0560 to fix?
Difficulty: easy. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0560 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
