Remember, the Knock Sensor keeps fuel from detonating in the cylinder … exploding rather than quickly burning as it should. If not replaced a faulty Knock Sensor can quite literally cause hundreds if not thousands of dollars in damage. There is really no need to look any further to find the Knock Sensor that’s application specific for your car, truck, van or SUV – high performance or family vehicle.

It is located on the engine block itself in the valley between the cylinder heads. The entire intake manifold has to come off to access it:

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.

Where is the knock sensor located at on a 2004 impala. 3.4l vin E

On a 3.4l Impala (2000 thru 2005),the knock sensor is right above the oil filter. There is only 1 knock sensor on the 3.4l engine. You need to drain the radiator to replace it. The 3.8l engine has 2 knock sensors.There are a lot of wrong answers on here so be careful.
