P0480: Cooling Fan 1 Control Circuit
8 vehicles · 6 makes · $150-$1,800 repair
Most Reported On
P0480 is an OBD-II diagnostic trouble code meaning “Cooling Fan 1 Control Circuit.” 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. This code is most commonly reported on 2009-2018 Audi A4, 2021-2023 Jeep Grand Wagoneer, and 2009-2013 Infiniti FX50, plus 5 other vehicles, with repair costs ranging from $150 to $1,800.
