If The engine in your van is a 3.5L, the knock sensor is under the upper intake manifold. This has to be removed in order to access the sensor on top of the engine block. The job requires an upper intake gasket set and about 1.5 hours to do; if you are handy with tools. For those who aren't; better off leaving this one to the professionals.

SOURCE: location of knock senor on 97 maxima se

Your knock sensor is located Under the hood, center, front engine area, below intake manifold, mounted on block.


A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark ****** than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.

To replace the knock sensor:

  • Disconnect the knock sensor wiring connector.
  • Then, unscrew the sensor.
  • Remove the knock sensor.
  • Reverse the procedures to install the part.

SOURCE: Looking to replace honda pilot knock sensor

These knock sensors are hard to get into. If thats a V6 it is underneath the intake manifold. make sure you cover the intake port when you take it apart, so a screw or a bolt don't accidentally drops in there.

Your sensor went off because it overknocked.
Try using a different type of fuel with a higher octane.
Erase the code and use the better gas. if it comes back then we will worry about replacing it.
