V90 Active Hood Fault Airbag Warning

My 2019 Volvo V90 hybrid is showing an "Active hood fault" message, and the airbag warning lamp is on. Diagnostic scans say the spring actuators have been triggered. Has anyone seen this, especially related to the impact sensor or pedestrian safety system?

I had a similar problem with my V90. Does the error come back immediately after you clear it?

Yes, the error reappears almost immediately. Did you figure out what caused the fault in your V90, and what diagnostic steps did you take?

Yeah, the error recurring right away is exactly what I experienced. I ended up taking mine to the workshop. Turned out to be the acceleration sensor. Best to get it checked out professionally.

I consulted my mechanic, and the issue was traced back to a defective acceleration sensor. The replacement, including labor, amounted to 315€. Thanks for pointing me in the right direction.
