P0480 MINI Code - Cooling Fan 1 Control Circuit Malfunction
Quick Answer
The electric cooling fan is controlled by the Engine Control Module (ECM) through the cooling fan relay based on inputs from the following components: - The engine coolant temperature (ECT) sensor - The intake air temperature (IAT) sensor - The A/C selector switch - The A/C refrigerant pressure sensor - The vehicle speed sensor (VSS) The ECM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. Common causes include Faulty fan control relay, Fan control relay harness is open or shorted, Fan control relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0480 MINI Description
- The engine coolant temperature (ECT) sensor
- The intake air temperature (IAT) sensor
- The A/C selector switch
- The A/C refrigerant pressure sensor
- The vehicle speed sensor (VSS)
The ECM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. The cooling fan relay will be commanded ON when the following conditions are met:
- The engine coolant temperature reaches 106°C (223°F) or more.
- The A/C clutch requested.
- The vehicle speed is less than 38 MPH.
The cooling fan relay will be commanded ON regardless of vehicle speed when the following conditions are met:
- The engine coolant temperature is 151°C (304°F) or more.
- The A/C refrigerant pressure is high.
The cooling fan may be commanded ON when the engine is not running under a fan run-on conditions described in the electric cooling fan general description portion of the service manual.
What are the Possible Causes of the DTC P0480 MINI?
- Faulty fan control relay
- Fan control relay harness is open or shorted
- Fan control relay circuit poor electrical connection
- Faulty cooling fan 1
- Fan cooling fan harness is open or shorted
- Fan cooling fan circuit poor electrical connection

Frequently Asked Questions about P0480 MINI Code
1. What does the OBDII code P0480 mean on a MINI?
P0480 indicates a malfunction in the cooling fan 1 control circuit, meaning the engine control module (ECM) has detected an issue with the fan's operation.
2. What are the common symptoms of code P0480 in a MINI?
Symptoms include the cooling fan not working, engine overheating, the air conditioning not functioning correctly, and the check engine light being illuminated.
3. What causes the P0480 code on a MINI?
Common causes include a faulty cooling fan relay, damaged wiring or connectors in the cooling fan circuit, a defective cooling fan motor, or a malfunctioning engine control module (ECM).
4. Can I drive my MINI with a P0480 code?
Driving with a P0480 code is not recommended, as it may lead to engine overheating, which can cause severe engine damage.
5. How do I diagnose the P0480 code in a MINI?
Start by checking the cooling fan relay, inspecting the wiring and connectors for damage or corrosion, testing the cooling fan motor, and verifying the ECM's control signal.
6. How do I fix the P0480 code on my MINI?
Repairs may include replacing a faulty cooling fan relay, repairing or replacing damaged wiring, replacing the cooling fan motor, or addressing issues with the ECM.
7. How much does it cost to repair the P0480 code on a MINI?
The cost depends on the exact issue, but replacing a cooling fan relay typically costs $50-$150, while a cooling fan motor replacement can range from $200-$500.
8. Can a blown fuse cause the P0480 code in a MINI?
Yes, a blown fuse in the cooling fan circuit can disrupt the fan's operation and trigger the P0480 code.
9. Will clearing the P0480 code fix the problem in my MINI?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
10. Can a faulty thermostat trigger the P0480 code in a MINI?
While rare, a faulty thermostat causing irregular coolant temperatures could indirectly affect cooling fan operation and contribute to the code.
