How to fix P0480 engine ode: Cooling Fan 1 Control Circuit Malfunction
A P0480 Code indicates that PCM has detected an incorrect amount of voltage (high or low) in the electric cooling fan control circuit.
The engine computer (ECM/PCM) detects a temperature increase through the coolant temperature sensor.
Once a set temperature is reached, ECM will activate the fan through the cooling fan relay.
If the ECM does not receive the correct amount of voltage from the cooling fan control circuit, it sets a P0480 Code.
Possible Causes of a P0480 Code:
Blown Fuse
Bad Relay
Wiring Open or Short
Bad Coolant Temperature Sensor
Bad Cooling Fan 1
Fan Control Module
