Knock sensors detect abnormal vibrations in the engine. The system is designed to reduce spark knock during periods of heavy detonation. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation.

the knock sensors are located in the top of the engine block. The intake has to be removed to get to the sensors.
They help control spark knock and the damage they can do.
There are two knock sensors on your engine, and they are underneath the intake manifold. You will have to remove the intake to get to the sensors.
The "knock sensors" for the Avalon 3.0 are facing the firewall on the engine block just below the cylinder head ,their are two knock sensors .
knock sensors operate the same in every vehicle. when the engine "pings" or called spark knock( due to bad gas or low octane fuel, carbon build up on top of pistons or valves) the knock sensor sees this and retards the timing. vehicles now days, timing is not adjustable by u or me, only through the computer using the knock sensor and other sensors. master tech 26 yrs.
Yes they can.
The knock sensors are located under the intake manifold on top of the block. You have to remove the entire intake manifold to get to the knock sensors. Good luck, I am in the process of changing mine as well.
you have to remove the intake, and there are 2 knock sensors.
under the intake. in the valley. 2 knock sensors actuallly
They are located down in the engine block valley. Accessing the knock sensors requires cylinder head removal..........sorry.
The 6.0L has 2 knock sensors and there both underneith the intake manifold. You can not see are get to them until you remove the intake.
