What it means
Causes include low coolant, a failed thermostat or water pump, a stuck cooling fan, a blocked radiator, or a head gasket failure. P0217 is a generic OBD-II powertrain code defined in the SAE J2012 standard, so it applies to virtually any 1996-or-newer petrol car or light truck regardless of make. Fix the underlying fault, then clear the code with an OBD-II scan tool — it will return if the problem isn't resolved.
Symptoms
- Check engine light + high temperature gauge
- Coolant loss, steam, or sweet smell
- Power loss / engine protection mode
