Want this question answered?
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 .
you have to remove the intake, and there are 2 knock sensors.
They are located down in the engine block valley. Accessing the knock sensors requires cylinder head removal..........sorry.
There's no need to replace knock sensors, and there was never a 3.6 engine.
Sienna's have two knock sensors located in the valley underneath the intake manifold. Replacement is a three hour job.
replace it.
Open the hood
There are two knock sensors on a 2001 Chevy 1500 with the 5.3 V8. You have to remove the intake manifold, because both of them are located under it. it is best to replace both knock sensors at one time, and you will need an intake manifold gasket too.

the knock sensors (there are 2 of them) are located under the intake manifold on the 5.3 engine,,,,,requires complete removal of manifold to replace.
the knock sensors are located in the top of the engine block. The intake has to be removed to get to the sensors.
you will need to remove the engine cover fuel rails and intake manifold unscrew the 2 knock sensors screw the new ones in and replace the manifold and fuel rails good to go...
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.
