When reversing, parking assist sensors (also known as backup sensors) alert drivers when they are approaching objects so they can safely park with ease. If a driver becomes reliant on their parking assist sensor to signal danger, it can impose real problems for them when parking without it. The main symptom of a faulty parking assist sensor is a squeaking noise and its absence when approaching an obstacle. Replacing the sensor is a fairly straight-forward task for someone with prior knowledge of working on vehicles. However, if you require assistance, it’s always best to consult a mechanic who will be able to adequately troubleshoot the problem.
