How do knock sensors detect abnormal vibration in the engine and How to check and replace them on Nissan Quest?

Knock sensors detect abnormal vibration in the engine and are part of a control system designed to reduce spark knock during heavy detonation, allowing for maximum spark advance to enhance driveability. These sensors produce AC output voltage that increases with the severity of the knock, sending a signal to the PCM to retard timing in response to severe detonation. To check a knock sensor, disconnect the KS sub-harness electrical connector located on the passenger side of the engine compartment next to the intake manifold. Use a voltmeter set to the lowest AC voltage scale, connecting the negative probe to ground and the positive probe to the sensor terminal on the sub-harness connector, typically identified by a white wire. Tap sharply on the intake manifold to simulate engine knock and observe voltage fluctuations; if none are detected, the sensor is faulty and needs replacement. To replace the sensor, remove the upper and lower intake manifold and the coolant crossover tube, unplug the electrical connector, and take out the sensor retaining bolt and the sensor from the engine block. Install the new sensor, tightening the retaining bolt to 18 to 25 ft-lbs, reconnect the electrical connector, and reinstall the intake manifold, refilling the cooling system as necessary.

Nissan Quest Knock Sensor

The Nissan Quest Knock Sensor picks up irregular vibration of the combustion engine and sends this information to the engine computer to allow the ignition timing to be adjusted before the ignition engine suffers any harm. The Knock Sensor is mounted on the engine block and has a piezoelectric element that transforms vibration into an electrical signal that is fast to detect the presence of spark knock. This signal is sent to the powertrain control module where ignition timing is retarded in small steps until no longer knocking is detected and ignition timing is again advanced to ensure that combustion remains efficient. Knock Sensor is applied in Nissan systems to maintain constant performance, fuel consumption, and low emissions without intervention. In the Quest model line the sensor functions continuously, monitoring all the cylinders in response to varying loads, fuel quality or ambient conditions. A faulty Knock Sensor could permit continued spark knock, reduced power, and the check engine light to stay on since timing is no longer able to be adjusted appropriately. In order to accommodate factory control strategies, Nissan defines a small single piece design of Quest vehicles which is a combination of sensing element, connector and mounting boss. The regular Knock Sensor operation allows the Nissan Quest engine to automatically control the detonation and provide stable work in different driving conditions.
