SOURCE: knock sensor code, p0330
The knock sensors either work or they don't. When they do not, the light comes on. All that a knock senor is is a piezo crystal that vibrates at the frequency that is comparable to engine "knock", and sends that yes/no signal to the ECU. There are 2 knock sensors, and both are bolted to each side of the engine interior walls, under each cylinder head. You have to remove both of the intake manifolds to access the knock sensors and their wiring.
Price to pay? My flat rate book suggests 3.7 hrs to change both. 3.7 hrs times your local labour rate, plus the price of the 2 sensors and/or wiring, and the price for the gaskets for the upper & lower manifolds. Depending on your location, you could quickly spend over $500.00.

The Knock sensor on a 22re is located under the intake manifold on the engine block. to the upper left of the oil filter. With is the passenger side of the engine. I believe it is yellow in color. Not do be confused with the oil pressure sensor which is close by. The knock sensor has a larger electrical connector. Good luck it can be hard to get to.
