The 2001 Chevrolet Suburban is equipped with one knock sensor. The knock sensor will be attached to the back of the engine.
the knock sensors are located in the top of the engine block. The intake has to be removed to get to the sensors.
Assuming this is the 4.3L engine, one.
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.
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.
They help control spark knock and the damage they can do.
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 .
It has 2 and both of them are underneith the intake manifold.
Yes they can.
