Do you need to replace the knock sensor?
Regardless if one or both codes are set, not only should the two original knock sensors be replaced, but you should also replace the harness. In fact, it will most likely shatter like glass when you attempt to disconnect it. The replacement harness comes complete with new connectors and boots.
Why is the knock sensor on my car only one wire?
If drive around with the check engine light on when a code P0332 or a P0327 is set in the computer memory, engine damage could occur. To me the most interesting part about the knock sensor is that it only has one wire going to it. The reason for this is the sensor generates its own voltage and is case grounded.
Is there a knock sensor problem on my Hummer?
In fact, if you have a 4.8 L 5.3 L or 6.0 L in any General Motors vehicle, including a Hummer or Pontiac, you will probably run into a check engine light indicating a defective knock sensor at some point.The check engine light registering a code P0332 or a P0327 is often the first sign you have this common problem.
How do you remove a knock sensor from a Camaro?
Remove the knock sensor plugs from the valley plate and disconnect the wiring harness assembly from the knock sensors. Figure 15. Knock sensor plug and wiring harness removal. Remove the knock sensors using a 22mm socket, extension and ratchet.

Where are the knock and Ping sensors located?
It’s a piezoelectric automotive sensor that produces a small voltage signal when it hears internal engine noise that we often call knock and ping. This is why the location of the two sensors is a problem. In order to hear the engine noise reliably the sensors are buried under the intake manifold.
Can a rodent damage a car knock sensor?
Rodent damage should be pretty easy to see. If the cables are good, then maybe the sensors are bad, but it does seem unlikely that both would go at the same moment. Owning 2 older vehicles makes lots of sense to me. It costs no more, and it gives you the time to do work like this.
