What does engine code P0481 mean?
control circuit for cooling fan 2
What the P0481 code means. P0481 is the OBD-II generic code for a problem with the control circuit for cooling fan 2. The cooling fan should be commanded on under certain conditions where the engine requires more cooling, and this is controlled via the cooling fan relay.
What does the p0480 code on my car mean?
What the P0480 code means. P0480 means that the cooling fan 1 control circuit has a malfunction. The vehicles ECU has tried to control the cooling fan 1 and it has failed to operate or a fault was detected. The ECU then triggers a Check Engine Light to illuminate on the dashboard.
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.

How does the p0480 GMC cooling fan control circuit work?
The P0480 code is detected when the Powertrain Control Module (PCM) detects that the commanded state of the driver and the actual state of the control circuit do not match. Engine Light ON (or Service Engine Soon Warning Light) The PCM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.
