Ford Escort knock sensor installation location needed and confirmation on interference engine status on Ford Escort

Some Ford Escort owners report experiencing confusion regarding the location and function of the knock sensor, which is typically found near the rear of the engine but can also be installed in alternate locations such as the center or sides of the cylinder block. This variability in installation can affect the sensor's signal pickup and sensitivity to engine knock. Additionally, some owners mistakenly believe that the presence of a knock sensor indicates whether their engine is interference or non-interference; however, the knock sensor's primary role is to detect engine knock and communicate with the engine control unit for ignition timing adjustments. To accurately determine the engine type, it is advisable for owners to consult the vehicle's manual or seek guidance from a certified mechanic.
