It depends on the engine... 2.5L is located under the coil pack/Ignition module on the rear of the motor. 2.8L is located on the rear of the motor, under the rear exhaust manifold. Be careful when taking out the sensor, it has a very small bolt holding it in, and the sensors are known to break off in the block. Very big pain to get the remnants out.

In a 1991 Pontiac 6000 LE, the knock sensor is typically located on the engine block, often near the intake manifold or cylinder head. It may be positioned on the driver's side of the engine, mounted to the block. For precise identification, it's best to consult the vehicle’s service manual or a repair guide specific to that model.
On the oil pan there is a cap you unscrew, and inside there is a "card board filter", that you would pull out and replace.
You might try the autozone website or the Pontiac partsman as he might be able to print it out for you, should be a picture of it under the hood of the car or in your owners manual if you still have it.
