This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's cooling fan. The fan helps keep the engine cool, and if it's not working right, the engine might get too hot.
The P0480 code indicates a malfunction in the electrical circuit that controls the engine's cooling fan.
The P0480 code is triggered when the Engine Control Module (ECM) detects a fault in the cooling fan control circuit. This could be due to a failure in the fan motor, relay, wiring, or the ECM itself. The fan is responsible for drawing air through the radiator to help regulate engine temperature.
• Engine overheating

• Faulty Engine Control Module (ECM)
ECM: Engine Control Module, the computer that controls engine functions.
Relay: An electrical switch that opens and closes under control of another electrical circuit.
• Check the cooling fan operation.
• Inspect the fan relay and fuse.
• Test the fan motor for proper function.
• Check wiring and connectors for damage or corrosion.
• Replace the cooling fan motor if faulty.
• Replace the cooling fan relay if defective.

Engine Performance
• Do not ignore the Check Engine Light.
• Monitor engine temperature to prevent overheating.
• Seek professional diagnosis if unsure.
Check vehicle warranty for coverage on cooling system components.
The P0480 code has been a common issue in vehicles with electric cooling fans since the introduction of OBD-II systems.
High – Engine overheating can cause severe damage if not addressed promptly.
Driving with an overheating engine can lead to engine failure and is unsafe. Address this issue immediately.
• Engine running
• Air conditioning on (if applicable)
The cooling fan is typically located at the front of the engine bay, behind the radiator.
Q: Can I drive my car with a P0480 code?
A: It's not recommended, as it can lead to engine overheating and potential damage.
Q: How do I know if my cooling fan is working?
A: You can listen for the fan running or visually inspect it when the engine is hot or the air conditioning is on.
