Barometer Error
DJI Drone
Severity: CriticalWhat Does This Error Mean?
Barometer Error means the drone's pressure-based altitude sensor has detected a fault. The barometer is used to hold altitude — without it the drone may climb or descend uncontrollably. Do not fly. Restart the drone and contact DJI support if the error persists.
Affected Models
- DJI Mini 3 Pro
- DJI Mavic 3
- DJI Air 2S
- DJI Mini 4 Pro
- DJI Phantom 4 Pro
- DJI Avata 2
Common Causes
- Barometer sensor blocked or covered by dirt or debris
- Barometer damaged in a crash
- Extreme temperature affecting sensor calibration
- Firmware issue causing false barometer fault
- Moisture ingress into the barometer port
How to Fix It
-
Power off the drone completely and allow it to cool if it was overheated.
Extreme temperatures can temporarily affect barometer readings. A 10-minute cool-down may clear the error.
-
Inspect the barometer intake port for blockage.
The barometer port is a small opening on the underside of most DJI drones. Clean gently with a soft brush.
-
Restart the drone in a stable, non-windy environment.
The barometer calibrates to ambient pressure at startup. Wind gusts during startup can cause calibration errors.
-
Update firmware to the latest version.
Some barometer errors are firmware-related and have been fixed in updates.
-
Contact DJI support if the error persists after all steps.
A persistent barometer error requires hardware service. Do not fly.
When to Call a Professional
Barometer Error that persists after a restart requires DJI repair. Do not fly a drone with a barometer fault — altitude control will be unreliable. DJI service can replace the barometer sensor.
Frequently Asked Questions
What does the barometer do on a DJI drone?
The barometer measures air pressure to calculate altitude. It helps the drone maintain a set height above the takeoff point automatically. Without a working barometer, the drone relies solely on GPS for altitude, which is less accurate.
Can strong wind affect the barometer?
Yes — strong wind passing over the barometer port can cause turbulent pressure readings. This is why DJI shields the barometer intake. If flying in strong wind causes barometer warnings, descend to a lower altitude where wind is calmer.
Can I fly without a working barometer?
No — altitude stability depends on the barometer. A failed barometer makes altitude control unpredictable. The drone may climb or descend without inputs. Do not fly until the barometer is repaired.
