    What do you mean "Knock Sensor"?
    Engine light ON can mean many things from OXY sensors to wind shield washer fluid. If you have over 60k on the car have a tech check the internal timing belt.

Code p0325

P0325 Knock Sensor 1 Circuit Malfunction
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.
Symptoms 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:
  • The knock sensor is faulty and needs to be replaced
  • There is a wiring short/fault in the knock sensor circuit

You need to change the knock sensor. The knock sensor advances or retarts timing until spark knock is eliminated. If the wire is not connect to the knock sensor you will get the knock sensor code. So make sure the wire is connected to the knock sensor. Please let me know what happens.

Nissan xterra knock sensor

It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.
