P0480 on Infiniti
Cooling Fan 1 Control Circuit
P0480 on Infiniti vehicles indicates cooling fan 1 control circuit. Au7o has documented this code across 2 Infiniti models — most commonly on FX50, M56. P0480 indicates a fault in the engine control module's circuit that operates cooling fan 1 (or the fan relay it drives). The computer detected an open, short, or out-of-range condition in the fan control output. Because the cooling fan helps prevent the engine from overheating — especially at idle, low speeds, or with the A/C on — a fan that won't run can lead to high coolant temperatures. It is worth addressing fairly promptly to avoid overheating, particularly in hot weather or stop-and-go traffic. Typical repair costs on Infiniti range from $300 to $1,800, depending on the specific model and root cause.
Common Causes of P0480
- •Faulty cooling fan relay
- •Failed cooling fan motor
- •Wiring damage, shorts, or corroded connectors in the fan circuit
- •Blown fuse or fusible link for the fan
- •Poor ground for the fan motor or relay
- •Faulty fan control module (where used)
- •PCM driver circuit fault (less common)
P0480 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.
