What are some common causes of the code?
Causes
of this P2560 code may include:
- Low coolant level (most likely)
- An air pocket in the cooling system
- Faulty coolant level sensor or switch
- Defective or damaged coolant level sensor/switch wiring
What are the troubleshooting steps for P2560?
The first step is to simply check the coolant level. If it is actually low (which is likely), refill the coolant and monitor it closely to see if it drops again.
The second step would be to search for Technical Service Bulletins (TSBs) for the specific vehicle by year, model, and engine/transmission configuration. In some circumstances, this can save you a lot of time in the long run by pointing you in the right direction.
If the coolant drops low and you add coolant, and it happens again and again, that indicates there is a problem. Perhaps the head gasket is faulty or there is a coolant leak somewhere.
If there is an air pocket in the cooling system, it can give you different codes like this one. If you recently changed the coolant but did not properly bleed the air from the system, do so now.
There is a slight possibility that this code is erroneous, but it is usually an informational code logged to record a low coolant level. This code may be set as a permanent code, which cannot be cleared from the vehicle’s system.
