Active hood fault Honda City

I'm getting an "Active hood fault" message on my 2017 Honda City (gasoline engine) with 79434 km. The airbag light is on, and diagnostics show an error. The spring actuators seem triggered. I suspect a bad acceleration sensor. Anyone seen this?

Summary of the thread

A 2017 Honda City is displaying an "Active hood fault" message, accompanied by an airbag warning light and diagnostic errors. The issue might be due to triggered spring actuators, with a suspected faulty acceleration sensor as the cause. A similar problem in another vehicle was resolved by replacing a faulty sensor and recalibrating the system, suggesting a similar approach for the Honda City. An appointment has been scheduled to replace the sensor and recalibrate the system.

Sounds like a headache! I had a similar issue with my 2019 Opel Astra, but with the emergency brake system. Same symptoms: warning lights and error codes. Did anything trigger it, like a hard bump?

Thanks! No, nothing like a bump triggered it. The fault just appeared while driving. Was your Opel issue sensor-related, and how did you fix it?

Yep, it was a faulty sensor in the emergency brake system. I tried some basic fixes, but I had to take it to a workshop. They replaced the sensor and recalibrated the system. Sounds like a sensor issue with your hood system too. I'd suggest a trusted mechanic.

Thanks for the advice! I've scheduled an appointment to replace the acceleration sensor and recalibrate the system. The estimated cost is 315€. I appreciate you sharing your experience!
