Under the intake manifold.
There are 2 knock sensors on these motors. They are located in the valley cover under the intake manifold.
you mean knock sensor
2003 chevy tahoe knock sensor
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.
Behind the starter.
The intake temperature sensor is located on the side of the air filter case on a 2003 Chevy Silverado 4.3 1500. It is on the top of the engine.

You probably mean the NOX sensor, it is the exhaust in front of the converter and the V8 has at least two of these sensors, easy to get to after you get under the truck, just unplug the wire and remove from the exhaust
There are 2 of them and they both are underneith the intake manifold.You will have to remove the intake to even get to them are see them.
That engine has 2 of them and you MUST remove the intake manifold to service the knock sensors.
