P0480 means the ECM detected an electrical fault on the primary cooling fan control circuit. The fan may not spin when commanded, so the engine can overheat at idle or in traffic and the A/C loses cooling capacity.

P0480 est un code defaut lie a systeme de refroidissement, classe en gravite moderate. Lorsque le calculateur de ton vehicule detecte cette condition, il enregistre P0480 et allume le voyant moteur.
Si ton vehicule a declenche P0480, tu peux remarquer un ou plusieurs de ces symptomes :
Voici les causes les plus courantes de P0480 :
Non, regle ca immediatement. You can drive short distances at highway speed where ram air cools the radiator, but stop-and-go traffic will overheat the engine within minutes. Fix it before your next commute.

5.4L Triton trucks are notorious for the shroud-mounted fan control module cooking itself from heat soak. Ford TSB 08-7-6 covers the exact symptom. Aftermarket Dorman module runs about €140.

Mk5 and Mk6 with the 2.0 TDI CBEA/CJAA use dual fans controlled by the J293 module bolted to the fan shroud. The plastic housing cracks, water gets in, and the primary circuit dies. VCDS often shows 00519 alongside P0480.

5.3L V8 GMT900 trucks with electric fans (not the mechanical clutch fan) commonly lose the fan relay in the underhood BEC. AC Delco relay is around €20. Check for the sibling code P0691 first.
2006-2013
N52 and N54 cars use a PWM pusher fan with the control electronics built into the shroud. Expect BMW-specific fault 2E7C alongside P0480. The complete assembly (part 17427562080 and equivalents) is €400 to €600.

8th and 9th gen Civics with the R18 rarely throw P0480 early in life. When they do past 150,000 km, it's almost always the radiator fan relay in the underhood fuse/relay box or a fan motor with worn brushes drawing over 20A.

Ces codes apparaissent souvent avec P0480 ou indiquent des problemes connexes :
On the highway, briefly. Ram air through the radiator does most of the cooling above 60 km/h. But in traffic or at idle you'll overheat within 5 to 10 minutes, and a warped head or blown gasket runs €1,500 or more.
Most ECMs default the fan to 100% as a fail-safe when they lose control authority over the circuit. It protects the engine while the fault is present and it's a strong hint the control side (relay, module, or driver) failed rather than the motor itself.
It's the single most common fix, roughly 40% of the cases I've seen, but not guaranteed. Test-swap the relay with an identical one from the same fuse box before buying anything. If that doesn't restore normal operation, move to the fuse, then the motor, then the wiring.
Usually yes. On most cars the primary fan doubles as the condenser fan. When it won't run, high-side pressure spikes at idle and the ECM either commands the compressor off or you just get warm air until you start moving.
Not directly. P0480 is a circuit-side electrical fault. A bad ECT sensor throws P0117 or P0118 and can make the fan behave oddly, but the ECM won't set P0480 unless it sees an actual open, short, or wrong feedback on the fan control line.
A flashing check engine light is not the same as a steady one. It almost always means an active misfire that can wreck your catalytic converter in minutes.
An unfamiliar light just appeared on your dashboard and you have no idea what it means. Here is how to read every symbol by colour and which ones mean stop now.
