I don't think Chevy changed the location of the knock sensor. On my 1994 4.3 its on the left hand (drivers side). There are 2 sensors there, one of them is the temp gauge sending unit and the other is the knock sensor.
Under the intake manifold there are 2 knock sensors
NO.

The knock sensor is located on top of the block in a 4.8 2002 engine. The intake will have to be removed to get to the sensor.
