Why does my car have an error code of p0480?
Aside from the illumination of the Check Engine light, the only obvious symptom of this error code is the increase of engine temperature as soon as the vehicle idles or stops, this is because the fans are not running to cool off the engine. There are multiple factors that can lead to this error code.
What does code p0481 mean on car cooling fan?
The vehicle’s PCM control the cooling fans, and the second that it determines the fans are not working properly, it triggers the code and illuminates the Check Engine light.
What’s the difference between p0480 and P0 482?
NOTE: P0480 speaks of the basic circuit, however codes P0481, and P0482 relate to the same problem with the only difference is they relate to the different fan speed relays. Check engine light (malfunction indicator lamp) illumination and code P0480 set
How does the p0480 cooling fan relay work?
The PCM (powertrain control module) senses the increase in engine temperature through the CTS (coolant temperature sensor) located near the thermostat. When the temperature reaches about 223-degrees F (value depends on make/model/engine), the PCM will command the cooling fan relay to turn on the fan.
