What fuse is for reversing sensors on c5?

On a Citroën C5, the fuse for the reversing sensors is typically located in the fuse box under the dashboard or in the engine compartment, depending on the model year. You should check the owner's manual for the exact fuse number and location, as it may vary between different trims and production years. Generally, it is labeled as "reversing sensors" or something similar. If you're unable to locate it, consulting a wiring diagram or a professional can help.
