What are the codes for a knock sensor?
Here is a photo of one knock sensor: If the knock sensor or associated wiring has failed or broken, you may see some of the following knock sensor related automotive repair trouble codes: P0325 – P0326 – P0327 – P0328 – P0329 – P0330 – P0331 – P0332 – P0333 – P0334
What happens when a Nissan knock sensor malfunctions?
When the sensor malfunctions, two common complaints become a noticeable lack of performance and a major decrease in miles per gallon. One of the things that shock me is the far-reaching number of automobiles affected by this Nissan knock sensor code. Any vehicle carrying the 3 L V-6 engines from 1990 through 1999 will eventually need this repair.
Can a bad knock sensor turn on an engine warning light?
Of course, there are many reasons why an engine warning light could turn on and a bad knock sensor is one of them. Regardless of the reason, you shouldn’t take the chance of ignoring it for too long or it could have devastating effects on your engine.
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.
What are the codes for the knock sensor?
Eventually this turns on the check engine light and sets the codes P0332 and P0327. Note that often either one or the other code will set. 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.
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.

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.
