Drive with caution — fix soon.
This code means the system has detected that the air conditioning refrigerant charge has dropped too low, typically because of a leak. It usually points to a leaking hose, fitting, condenser, or compressor seal that lets refrigerant escape. The fix involves finding and sealing the leak, then recharging the system to the correct level.
$150 – $600
Varies by vehicle and root cause.
Yes. This code is about A/C refrigerant, not engine or brake safety, so it's fine to drive. You'll mostly notice weak or no cooling. Get the leak repaired before hot weather makes the lack of A/C unbearable.
Costs usually run from $150 to $600. A simple leak repair and recharge is on the low end, while replacing a condenser or compressor seal raises the price. Finding the leak first is essential so a recharge actually lasts.
It's moderate. It won't harm your engine or safety, but running the A/C low on refrigerant can damage the compressor over time. Fixing the leak protects the compressor and restores cooling.
Refrigerant doesn't get used up, so a loss almost always means a leak somewhere in the system. Common spots are hose connections, O-rings, the condenser, or the compressor seal. A shop uses dye or an electronic detector to find the exact leak before recharging.
