Genuine Nissan Titan Knock Sensor

Nissan Titan Knock Sensor is a device that measures the vibrations of the engine in order to detect detonation and transmitted the information to the powertrain control module in order to adjust ignition timing to achieve a smooth combustion. The Knock Sensor is attached to the engine block and it consists of piezoelectric element that converts pressure pulses generated by abnormal combustion into an electrical signal. In the presence of knock, the module retards timing in small steps until knocking ceases, and then gradually resumes timing to maintain the engine at approximately the same speed as its knock limit, maintaining its performance but avoiding component damage. Since the Nissan Titan ignition system is computer controlled, Knock Sensor is instrumental in sustaining power, fuel efficiency, and control of emissions in different grades of fuel, differences in temperature and load. On certain models the control unit is able to set timing cylinder per cylinder and on turbocharged units it can also control boost pressure depending on Knock Sensor feedback, but the core feedback strategy is the same on all Nissan Titan. Frequent operation of Knock Sensor will assist in making sure that all Nissan Titan will start easily, run smoothly, and will not be damaged as a result of detonation.
