I've replaced the knock sensors 3 times in my 02 Silverado 5.3 and it's reading low on bank 2 again what can be done about this? I replaced harness and both sensors 3 times and still same thing and it's not wet.
AGREED!!!!Is it possible the knock sensors are going bad due to an actual knock issue? Have you check the spark plugs, is there a substantial build up of carbon in the engine, is the timing advanced too much, etc?
What are the actual codes you get when the knock sensor goes? What's the time line between failure?
