Why's my Porsche Macan backup camera not working?

If the backup camera is not working in Your Porsche Macan it could be due to faulty wiring or sensors or both. The faulty sensor might send a wrong signal to the computer, leading to a miscalculation in the engine timing and fuel calculation. If the computer keeps receiving a cold signal from the faulty sensor, it will interpret this as if the engine is cold and continue to inject more fuel.If Your car doesn't currently have a backup camera, also called a rearview camera, it's likely that Your next new vehicle will. As of May 2018, federal law has required that all new passenger cars, trucks, vans and other vehicles weighing less than 10,000 pounds be equipped with rearview monitoring technology.
