For 4.2L V6 models, the knock sensor is installed in front of the exhaust port on the engine head, in front of the left cylinder. First, pull the negative wire off the battery terminal. To get to the knock sensor, loosen the single bolt which holds the fuel supply line to the transmission bell housing and pull the line out and upward slightly. Lose the electrical connector from the knock sensor, undo the mounting bolt and then pull out the knock sensor. Installation is in the reverse order with a particular emphasis to tightening the knock sensor to the appropriate torque. For 3.5L, 3.7L V6 and all V8 models the knock sensor(s) are located in the valley between the cylinder heads below the intake manifold, which must be removed to get at. Reduce the fuel system pressure and remove the cable of the negative terminal of the battery. Remove the intake manifold. Undo the electrical connector from the knock sensor by pressing down the locking tab; for 5.4L V8 engines, there are two knock sensors with their related connectors; the 4.6L V8 engines only use a knock sensor positioned at the right cylinder head. This involves the removing of the retaining bolt that holds the knock sensor in place on the engine block the knock sensor is then pulled out. Again, installation is the reverse of removal and it is done with an equal torque on the retaining bolt.

Ford F-150 Knock Sensor

The Knocks Sensor in Ford F-150 is vital in the performance of the engine since it is used in detecting engine knock that is caused by wrong ignition timing. It transmits information to the power train control module, the PCM so that the latter can be able to alter ignition timing to reduce detonation. Normally, Ford F-150 applies the knock sensors that use piezoelectric effect to sense vibrations, which introduces electrical signals and enables to control pressure peaks that signify knocking. The knock sensing and control technologies used in Ford F-150 vehicles over the years include, cylinder specific ignition timing adjustments, boost pressure control depending on the design of the engine. This helps in achieving max r.p.m with no knocking and lasting long life for the engine all if used at low octane rating. Case analysis of the Knock Sensor in the Ford F-150 models shows how engine efficiency and protection from damage under trim driving conditions must be managed in the course of product development.

We provide a wide range of Ford F-150 Knock Sensor at the best prices possible. If you need Ford F-150 Knock Sensor, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
