In a Ford Fiesta, there are multiple crash sensors strategically placed - one behind the central front bumper and one on each side between the doors. These sensors play a vital role in safety by relaying impact information to the airbag system. Depending on the sensor triggered, the system will deploy either the front or side airbags. It is crucial to ensure that these sensors are functioning properly to avoid airbag failure in an accident. Before replacing any of these sensors, it is imperative to disconnect the negative battery terminal and let the car sit for at least an hour to release any stored electricity. Failing to do so could inadvertently trigger the airbags during maintenance work.
The crash sensor for the Ford Fiesta can be found in the front bumper.
