DJI Barometer Error — What It Means & How to Fix It

What it means

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.
