Whether you’re driving a new or used Silverado, you may have encountered a trouble code P0327. This trouble code indicates that the knock sensor has been damaged.

The knock sensor is responsible for the engine’s ability to detect detonation. Without it, the car won’t be able to properly curve its power output and timing. In order to fix this problem, you need to replace the knock sensor or fix a wiring harness issue.

While the knock sensor is a small part of the engine, it plays the role of the vehicle’s ear to the computer. The sensor is mounted on the cylinder head, intake manifold, or engine block, and it listens for irregular noises.

If you ignore a knock sensor code, it can result in increased emissions and a loss of gas mileage. Even worse, if you ignore it, you may risk costly damage to your vehicle.

The knock sensor is one of the most common causes of P0327. Essentially, a low knock sensor signal tells the computer that a knock sensor is missing. However, when this sensor is damaged, the computer will think the knock sensor is missing and treat the vehicle accordingly.

The knock sensor is often bolted into the engine block, and their close proximity to the engine means they can be easily damaged.

P0327 is usually triggered by a knock sensor on bank one. The knock sensor’s internal resistance ranges from 9.3 to 107 K Ohms. The knock sensor will only work properly if the PCM detects a knock sensor problem.

Once it has been identified, the knock sensor will need to be replaced. Sometimes, the only symptoms of this error code are an illuminated check engine light.

The solution for the problem causing the code will depend on what is causing it. However, the solution will vary based on the make and model of your vehicle. Hence, it is important to know the cause of the problem before attempting to repair it.

However, it’s essential to get a mechanic’s opinion to make the right decision. If you suspect that the code is related to a wiring problem, it is best to have it checked by a mechanic.


There are several reasons that you may be getting a P0327 code in your Chevrolet Silverado. These errors are triggered by knock sensors. The proper way to repair knock sensors depends on the make and model of your vehicle.

To fix your vehicle, first determine the cause of the error code and then follow the right procedure. Here are some solutions to your problem. Keep reading to discover how to fix a P0327 code in your Chevy Silverado.

Otherwise, you must find a replacement or repair the wiring harness. If this does not work, you can try to replace the knock sensor. This is a relatively easy fix, but it will be time-consuming and a pain.

The knock sensor is responsible for generating the P0327 trouble code. The internal resistance of this sensor is 9.3 to 107 K Ohms. The computer will then act as if it was not present.

The knock sensor is usually bolted into the engine block, so it is susceptible to damage. It is essential to look at the wiring harness and knock sensor to identify if any of them is damaged.

To resolve the problem, you must replace the knock sensor on Bank #1. Depending on the model, the knock sensor can generate low output voltage, triggering the P0327 DTC.

Other knock sensor-related DTC codes are P0326, P0327, P0329, and P0334. The symptoms associated with knock sensor-related codes include loss of power, hesitation, and low power.
