For 3.7L V6, 4.6L and 5.0L V8 engines sensors are located in the valley between the cylinder heads, under the intake manifold and that requires removing the intake manifold to access either of them. These engines are fitted with two knock sensors which are in a single harness and connector and hence must be replaced as a pair. First of all, unscrew the cable from the negative battery connection then take of the intake manifold. Follow the two leads coming from the knock sensors to the electrical connector that joins the two of them and cut that. Loosen the knock sensor retaining bolts, and while on 4.6L V8 engines, the two knock sensors have different electrical leads but are connected to a single electrical connector therefore have to be removed or replaced as a pair. Reinstallation proceeds in the reverse manner to the removal process so as to ensure that knock sensor retaining bolts are tightened to the recommended torque.

Ford Mustang Knock Sensor

Knock Sensor helps in effective performance of Ford Mustang automobiles because it is responsible for measuring the knock, which is a result of wrong timing of ignition. This device communicates with the powertrain control module (PCM) and allows it to change the ignition timing in order reduce high detonation. Usually, the Ford Mustang Knock Sensors use piezoelectric technology to convert the physical vibration into the electrical signals to check constant pressure spike, which signifies knocking. Through the years Ford Mustang has used different designs of Knock Sensors, which are mainly directed to improving the ability and effectiveness of the engine. Contemporary systems are able to act upon ignition timing for each cylinder and can also control boost pressure in some specific cases. It also allows the Ford Mustang to run smoothly at different conditions while at the same time protecting the engine from damage and offering a chance for using fuel with a lower octane number.
