Need to know how to install knock sensors and where they are need diagram. 2005 expedition 5.4 engine


Hello adamjerkins,

It is somewhat complicated to change the knock sensors. There are two of them and they are located under the intake manifold. The intake manifold must be removed. I would recommend tha you replace both while you have the engine apart.

What leads you to believe the knock sensors are bad, I've seen few bad knock sensors? The knock sensor issues more times than not have been caused by other problems.

After you remove the intake manifold disconnect the knock sensor connectors. Remove the bolts and the two knock sensors then replace with new knock sensors tighten the bolts to 15 foot pounds. Reinstall manifold. The total job for an experienced mechanic with tools is about 5 hours. Not a good job for a beginner.

How to replace knock sensor on 1994 Lexus ES300


Hi,

This is a big job, you will need to remove the intake manifold and various other intake components to get to the knock sensor, which is sitting in the V gulley of the engine.

But basically you need to remove all inlet tract components, and the top cooling system components, then remove inlet manifold and there you will see the knock sensor.

Good Luck

Thanks

How to repalce a knock sensor on my 2004 gmc yukon


Hi welcom to fixya. 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.
  • 15 ft.lbs.torque
  • hope this helps.Thank You for using fixya..iluv2fish.. Ray..

2005 suburban knock sensor, where are they located and how do I change them


the knock sensors are located under intake there is two so best to replace both while you have tore down. what usually happens is moisture builds up and causes bad connection. to remove intake remove fuel lines after bleeding pressure!!! all obvious hoses and wiring and i think it is 10 bolts holding intake down. let me know if you need more help

Where is the knock sensor 2 (bank 2) located on a 2000 chevy silverado 5.3? Can you send me a diagram?


I don't have a diagram but they are under your intake manifold. It's not to bad of a job. You don't have to remove the fuel rails or the injectors, they can come up with the intake. The #2 knock sensor is the one in the rear. I will suggest getting both of them and also the harness and do it all while you have it apart. I believe you will find that water has gotten down in the hole where the knock sensors are located. Make sure to clean it out very good with compressed air before you install your new knock sensors.

Knock-knock-knock front end of drivers side only under power and hard right turns only not left. but it comes and goes away? help


Sounds like your outer CV joint on the drivers side is worn. If so not really a DIY job. When shaft is removed you will loose g/box oil. plus hub has to be partially removed. Then the joint removed from shaft. Big job. would recommend going to see your local CV shaft shop.
