P0480 Fan 1 Control Circuit
Cooling
P0480 means there's a fault in the cooling fan's control circuit, so the fan may not run and the engine can overheat in traffic.
The engine computer found a fault in the circuit that controls cooling fan 1 (usually the low-speed fan relay or fan control module).
Watch the temperature gauge, especially in traffic and with the AC on. If the gauge climbs, pull over and shut the engine off. Get it fixed soon.
Common causes
- A failed fan relay
- A blown fan fuse
- A failed fan control module (on some vehicles)
- Damaged wiring or a corroded connector
- A failed fan motor
Symptoms
- Overheating in traffic or at idle
- AC blowing warm at idle
- Fan not running, or running all the time
What to check first
- Check the fan fuses and swap the fan relay with an identical one.
- Turn the AC on with the engine running; the fan should come on.
- Check the fan motor's connector and wiring.
- Check the fan control module if your vehicle has one.
