Nissan 22060-7S000 Knock Sensor

The knock sensor is located on the side of the engine block ahead of the car depending on one's side of the car. First, release the harness connector near the knock sensor area and pull it off. The next step is to unscrew the sensor mounting bolt and then utilizing the nut driver, unscrew the sensor. the real procedure of installation is the reverse of the removal process and it is essential to tighten the mounting bolt to 17 ft-lb.

The knock sensor is located on the engine block's side and is positioned towards the vehicle's front below the manifold. It can be found below the intake manifold, on the engine block, on the side that faces the radiator. To take it away from there, initially disconnect its electric connector. Thereafter pull out a sensor mounting bolt and sensor itself. Put it back through reversing procedures which were used to remove it. Finally, make sure you tighten bolt mounting to 17 ft-lbs.

First of all, detach the cable from the battery terminal, the negative terminal. Remove the intake manifold. Then, disconnect the knock sensor electrical connector. After that, unscrew the knock sensor bolt and undo the sensor. The installation procedure is the reverse of removal.

The knock sensor detects abnormal vibration (spark knock or pinging) in the engine. The knock control system is designed to reduce spark knock during periods of heavy detonation. This allows the engine to use maximum spark advance to improve driveability. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation. On 1993 and 1994 models, the knock sensor is located on the right (rear) side of the engine block below the exhaust manifold. On 1995 and later models, the knock sensor is located below the intake manifold. To check, disconnect the knock sensor harness connector. Using an ohm-meter, check for continuity between the two terminals of the knock sensor connector. Continuity should be indicated. If an open circuit is indicated, replace the knock sensor. The knock sensor resistance is very high, use an ohmmeter cable of measuring at least 10 M-ohms. For 1993 and 1994 models, wait for the engine to cool completely before performing this procedure. Drain the cooling system. Raise the vehicle and support it securely on jackstands. Disconnect the knock sensor harness connector and detach any retaining clips. Remove the knock sensor from the engine block. Installation is the reverse of removal. Refill the cooling system. For 1995 and later models, remove the upper and lower intake manifold. Where necessary for access, remove the lower intake manifold as well. Disconnect the electrical connector from the knock sensor. Remove the sensor retaining bolt and the sensor from the engine block. Installation is the reverse of removal. Install the intake manifold.

Disconnect the knock sensor electrical connector.
