What does a radiator fan control module do?
What does a radiator fan control module do?
An A/C fan control module helps to control the blower that supplies air to the cabin of a vehicle, as well as the cooling fans. The module helps to make sure that the cool air that is produced within the A/C system of a car is blown into the cabin.
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.
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.
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
Why does my car overheat while sitting still?
It does so by supplying the ground to the relay. There is a problem within this circuit causing the fan to fail to operate allowing the engine to overheat while sitting still or driving at a slow speed. When the PCM attempts to activate the fan and senses the command and the result do not match, the code is set.
