P0482

Fan 3 Control Circuit

Q: Is it safe to drive with P0482?

Only with caution. If a cooling fan is dead the engine can overheat when you're idling or in traffic. Keep an eye on the temperature gauge and fix it promptly.

Q: Can I just clear P0482?

It returns until the fan circuit is repaired, and clearing it doesn't restore cooling. Address the root cause.

Engine cooling Generic OBD-II High

What it means

P0482 means the ECM has detected a fault in the control circuit for cooling fan 3. Cooling fans pull air through the radiator (and condenser) at low speed and when idling, so a fan that won't run can let the engine overheat in traffic and weaken A/C performance. The cause is usually the fan motor, its wiring, or the fan control module.

High

Can I keep driving? Watch the temperature gauge — if a cooling fan isn't running the engine can overheat in slow traffic or idling. Avoid stop-and-go driving until it's fixed.

How to diagnose & fix

Work through it in order

Read freeze-frame data and confirm the code with a scan tool.
Check the fan fuse and relay first, then command the fan on to see if it runs.
Inspect the fan motor wiring and connector for damage or corrosion.
Test the fan motor directly with power and ground; replace it if it won't spin.
If the motor and wiring are good, suspect the fan control module. Clear and re-test.
