P0480 Lincoln Code - Fan 1 Control Circuit Malfunction
Quick Answer
The electric cooling fan is controlled by the Powertrain Control Module (PCM) 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 PCM 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 Lincoln 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 PCM 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.
The PCM monitors the Low Fan Control (LFC) primary circuit output. The PCM sets the OBDII code when the Low Fan Control (LFC) signal is not to factory specifications.
What are the Possible Causes of the DTC P0480 Lincoln?
- 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
- Faulty Powertrain Control Module (PCM)
