Look under exhaust manifold on drivers side, closer to rear of engine, mounted on engine block.

Keep in mind that the knock sensor is a tuned piezoelectric crystal transducer that is located in the cylinder head. The knock sensor provides the MCU with an electrical signal that is created by vibrations that correspond to its center frequency (5550 Hz). Vibrations from engine knock (detonation) cause the crystal inside the sensor to vibrate and produce an electrical signal that is used by the MCU to selectively ****** the ignition timing of any single cylinder or combination of cylinders to eliminate the knock condition.

This and other details can find in the Grand Cherokee Service Manual.

Good luck (remember rated this).

Where is the knock sensor on 2003 honda crv

The knock sensor on a 2003 Honda CRV is located on the engine block. Specifically, it is located under the intake manifold, which means it can be difficult to access. Here are the steps to locate and replace the knock sensor on a 2003 Honda CRV:
  1. Disconnect the negative battery cable to prevent electrical shock.
  2. Remove the intake manifold. This involves removing several bolts and electrical connections.
  3. Locate the knock sensor, which is located near the rear of the engine block, under the intake manifold.
  4. Disconnect the electrical connector from the sensor.
  5. Remove the sensor from the engine block. This may require a special tool, depending on the specific design of the sensor.
  6. Install the new knock sensor, making sure it is properly aligned and tightened to the correct torque specification.
  7. Reconnect the electrical connector to the sensor.
  8. Reinstall the intake manifold, making sure all bolts and electrical connections are properly secured.
  9. Reconnect the negative battery cable.
Note that if you are not experienced with working on engines or are unsure of how to proceed, it may be best to seek the assistance of a qualified mechanic to replace the knock sensor on your 2003 Honda CRV.

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.
