PlayStation Error Code CE-40840-3 — What It Means & How to Fix It

What Does This Error Mean?

CE-40840-3 means your PS5 encountered an error while running a game or application and had to close it. The game crashed unexpectedly. This is most often caused by corrupted game data, an outdated game version, or overheating — not a broken console.

Affected Models

PlayStation 5
PlayStation 5 Digital Edition

Common Causes

The game's installed data has become corrupted
The game has not been updated to the latest version and contains a known crash bug
The PS5 is overheating due to poor ventilation or a dusty cooling system
The expanded M.2 SSD (if installed) has a compatibility or speed issue
The PS5's system software needs an update to improve game compatibility

How to Fix It

Update the game. Press the Options button on the game in your Library and select Check for Update. Install any available updates before playing.

Game publishers regularly release patches that fix crash bugs. Many CE-40840-3 errors are caused by a known bug that was already patched.
Check for corrupted data. Go to Settings > Storage > Console Storage > Games and Apps. Highlight the affected game, press Options, and select Check for Corrupted Data.

If corruption is found, delete the game and redownload it from your Game Library. Your save data will not be affected.
Check the PS5's ventilation. Make sure the console is in a well-ventilated area with at least 10 cm of space on all sides. Do not place it in a TV cabinet without airflow.

The PS5 generates a lot of heat. Overheating causes crashes that look like software errors.
Update the PS5 system software. Go to Settings > System > System Software > System Software Update and Settings > Update System Software.

Sony releases PS5 firmware updates that improve game compatibility and stability. Running an old system version can cause games to crash.
Rebuild the PS5 database. Turn off the PS5 completely. Hold the power button until you hear two beeps to enter Safe Mode. Select Clear Cache and Rebuild Database.

This reorganises the PS5's file system and can resolve crashes caused by database corruption.

When to Call a Professional

CE-40840-3 is usually a software or game-specific issue. If it happens on multiple different games and persists after cleaning and updating, contact Sony Support. Persistent crashes across all games can occasionally point to a hardware fault that needs professional diagnosis.

Frequently Asked Questions

Is CE-40840-3 more common with certain games?

Yes. Some games are more prone to this error, particularly at launch before the developer releases stability patches. If a specific game always crashes, check the developer's social media or support page for known issues. Playing the same game after an update often resolves the crashes completely.

How do I know if my PS5 is overheating?

The PS5 will display an overheating warning on screen if temperatures become dangerous. You may also notice the fan running very loudly before a crash. If the console is warm to the touch on the sides or bottom, improve its ventilation immediately.

Can a faulty M.2 SSD expansion drive cause CE-40840-3?

Yes. If you installed an M.2 SSD expansion drive, a drive that is too slow, not properly seated, or incompatible can cause games stored on it to crash. Try moving the affected game to the internal SSD and see if the crashes stop. Check Sony's list of compatible M.2 drives on their support website.
