Drive with caution — fix soon.
This code means the engine computer detected a problem in the control circuit for cooling fan 2, the secondary fan that helps cool the engine and A/C. It usually points to a failed fan motor, faulty relay, blown fuse, or wiring issues in the fan circuit. It's commonly fixed by replacing the relay, fan motor, or repairing the wiring.
$150 – $700
Varies by vehicle and root cause.
Short highway trips in cool weather are usually fine, but the second fan matters most in traffic and at idle. Watch your temperature gauge and pull over if it climbs. Repair it soon to avoid overheating.
Expect roughly $150 to $700. A relay or fuse is cheap, while replacing the fan motor or control module costs more, plus labor depending on your vehicle.
It can be if the fan stays off, since the engine can overheat in slow traffic. With one fan still working you may be okay short term, but it's best fixed promptly.
It's the secondary cooling fan that adds extra airflow over the radiator, often kicking in during high heat, heavy A/C use, or slow traffic. When its circuit fails, cooling capacity drops and this code sets.
