SOURCE: 92 lexus es300 knock sensor

Need to remove the upper and lower air intake manifold.  There are two knock sensors for the front and rear pistons banks.  If you plan to do this yourself it is about 1 to 2 hours.  While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it.  Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300.  Pretty easy.

My 2000 lexus es 300 will not shift into overdrive while driving is there an easy fix.


I just had the same thing happen to me. Took the car to the dealership to ensure that I was putting money where the money needed to go. Turns out that I have a bad knock sensor that needs to be replaced. Not an easy fix. Garage/mechanic comparisons range from local garages (TN) from $700-$900. Hope this helps.

Has anyone ever replaced knock sensors on 98 lexus es300


yes, I have they are located between the 2 banks of the motor. you need to remove the upper intake manifold to get to them. not hard to do. Also its a good idea to replace the mini harness with them.
