P0217 on Infiniti
Engine Overtemperature Condition
P0217 on Infiniti vehicles indicates engine overtemperature condition. Au7o has documented this code across 2 Infiniti models — most commonly on FX50, M56. This code sets when the engine control module detects that the engine has exceeded its safe operating temperature, meaning the engine is overheating based on the coolant temperature sensor reading. Because excessive heat can warp the cylinder head, blow the head gasket, or seize the engine, the computer flags this condition and may reduce power to protect the engine. It generally indicates a real cooling system problem rather than just a sensor glitch, though a faulty sensor can occasionally cause a false reading. An overheating engine should be stopped as soon as it is safe to avoid serious damage. Typical repair costs on Infiniti range from $300 to $1,800, depending on the specific model and root cause.
Common Causes of P0217
- •Low coolant level or a leak in the cooling system
- •Stuck-closed thermostat
- •Failed water pump
- •Faulty radiator cooling fan or fan circuit
- •Clogged or blocked radiator
- •Faulty coolant temperature sensor giving a false high reading
- •Head gasket failure or combustion gases in the coolant
- •Air pocket in the cooling system after service
P0217 on Infiniti by Model
Infiniti FX50(1 issue)
- Radiator / Cooling Fan Related Overheating2009-2013
As these vehicles age, cooling system issues such as radiator seepage, fan control problems, or thermostat degradation can lead to elevated engine temperatures. The VK50VE V8 runs hot under load, so any reduction in cooling efficiency can quickly cause overheating, especially in traffic or hot climates.
Infiniti M56(1 issue)
- Radiator / Cooling Fan Module Failure2011-2013
M56 owners report overheating or rising coolant temperature caused by radiator leakage and/or electric cooling fan control failure. The issue is typically related to age-related plastic tank cracking, fan motor wear, or failure of the integrated fan control assembly, especially in hot climates or stop-and-go driving.
