did you see it or is it from the lips of others?

It does sound like the sensor may be bad, but you also need to check the wiring.
This information comes from:

http://www.obd-codes.com/p0325

P0325 OBD-II Trouble Code Technical Description

Knock Sensor Circuit Malfunction
What does that mean?

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes

A code P0325 most likely means one or more of the following has happened:

Possible Solutions
  • Check the resistance of the knock sensor (compare it to factory specs)
  • Check for broken/frayed wires leading to the sensor
  • Replace the knock sensor

On the Nissan that code means you have a short in the knock sensor circuit or you just need a new knock sensor.

A P0325 refers to the knock sensor electrical circuit, not the sensor itself! So check all wiring & connectors leading to the sensor, back to the PCM. Good luck, I found a good P0325 article here - http://www.obd-codes.com/p0325

Trouble code P0325 and P1444


Nissan code:
P1444 Canister Purge Volume Control Solenoid Valve

Generic OBD II code:
DTC Codes - P0300-P0399 – Ignition System or Misfire
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)

I hopes this helps you.
Replace or fix these two items should do the trick.
It's hard to diagnose a car over a computer.
