Error code P0480 means there is a problem with your vehicle’s engine cooling fan control circuit. In other words, your car’s computer (the PCM) is trying to turn on the cooling fan, but there is an issue preventing it from working correctly.
Here is a simpler explanation:
- The cooling fan is important for preventing your engine from overheating, especially when the car is idling or moving slowly and air is not flowing well through the radiator.
- The car’s computer (PCM) monitors the engine temperature. When it gets too hot, it sends a signal to turn on the fan.
- The P0480 code appears when the computer tries to turn on the fan but does not receive confirmation that the fan is operating.
In summary, code P0480 indicates a problem in the electrical circuit that controls your engine’s cooling fan. This could be due to a faulty relay, a wiring issue, a blown fuse, the fan itself being broken, or even a problem with the temperature sensor or the car’s computer (although this is less common).
It is important to fix this issue quickly, as a cooling fan that is not working can lead to engine overheating, which can cause expensive damage.
