What does a knock sensor on a car do?
The knock sensor has a very simple and straightforward job. It’s in charge of looking out for any signs of engine knocking in your car and alerting you to it if it’s going on. When your knock sensor detects knocking in your car’s engine, it’ll send the knock sensor code to your car’s main computer so that you know you have to do something about it.

What does DTC stand for on knock sensor?
Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0325 is set, this means that the knock sensor 1 in Bank 1 is not operating properly.

What causes a cylinder to have a misfire code?
When you have a misfire code for a particular cylinder, you can focus on one of three things: an ignition problem, a fuel injector problem or a compression problem. Every time a spark plug fires, the spark burns a few molecules of metal off the plug’s electrodes.

Why do I need a knock sensor on my engine?
Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged. When the engine “knocks” there is an excessive amount of NOx that is released.
How can I tell if my engine is misfired?
Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. A flashing check engine light and a P0301 to P0312 diagnostic trouble code (DTC) is a surefire indication that one or more cylinders are misfiring.
How many knock sensors are on a V6 engine?
Typically you’ll have one knock sensor on each bank of the engine (one on inline 4/5/6 cylinder engines, two on V6, V8, V10 engines). Here is a photo of one knock sensor:

Can a shorted knock sensor cause a fault?
But I can say that the scenario for a shorted knock sensor (a common failure on Nissan V-6 engines) to cause a fault code P0500 for a Vehicle Speed Sensor would involve a rodent eating wire insulation off of your engine harness causing some crossed wires. Or some other strange thing. Not impossible, but certainly far from probable.
Code P0325 sets when the PCM determines the knock sensor signal falls outside of a predetermined threshold for a certain amount of time. The ‘Bank 1’ portion of the code indicates that the issue pertains to the knock sensor on the side of the engine that houses the number one cylinder.
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.
