Hi! I have an 06 Saturn Vue with the Honda 3.5 engine in it, does anyone know where the knock detonation sensor is located on this engine? I am not sure if I am saying it correctly. It might just be called the knock sensor I am having a hard time finding this, so any help would be appreciated. Thank you!

It should be under the intake manifold, do you have a code for the knock sensor? I have seen rodents chew the wires to them. They nest under the manifold and chew the wires to the knock sensor. I have seen the wire to it chewed far more often then the sensor itself going bad.

Also I have replaced the knock sensor and the harness without removing the I take manifold before. Your engine is a interference fit engine. But if the timing belt is off by one tooth you could have a rough idle and run fine down the road.

Hi i'm Danny.

I have attached pictures below of the 4 cylinder and 6 cylinder engine knock sensor location as it did not specify. I am attaching a tutorial showing what the replacement entails, but it is in English. The 4-cylinder image is # 3 and the 6-cylinder image is location # 9.

Hope this helps and thanks for using 2CarPros.
