Did you have the check engine light reset after replacing it? if not then go to auto zone, and let them know you replaced it and need to reset the trouble light for the check engine light... hope this helps...

The code P1326 stands for "Knock Sensor Circuit Malfunction (Bank 2)". This code indicates that the engine control module (ECM) has detected a problem with the knock sensor circuit on the second bank of cylinders. A knock sensor is used to detect engine knock or detonation and adjusts ignition timing accordingly. If the knock sensor is not working correctly, it can cause problems with engine performance and starting.
If you have a code P1326 showing up, there are a few things you can try:
Check the wiring and connections of the knock sensor. Look for any damaged or corroded wires or connections.
Clean the sensor, if it is dirty or covered with debris, cleaning it may solve the problem.
Replace the sensor if it is faulty.
It's important to note that code P1326 can also be caused by other problems such as low compression, vacuum leaks or incorrect ignition timing, so it's important to have a professional diagnose the issue before replacing any parts.
It's also possible that the engine control module may need to be reprogrammed or updated to match the new engine, which would require an expert. It's always recommended to take the car to a professional mechanic to diagnose and fix the problem.
Yes, the ignition timing could be off enough to cause the symptoms and the check engine light. I would take it back to the shop and tell them to set base timing, clear the code, and refund you the cost of the knock sensor and labor.
No I don't think so, knock sensor only work under engine load, when sensor picks up a ping or knocking, it will adjust timing, o2 sensor could be bad, and will save you fuel mileage, but a miss will also give you an o2 sensor code, running rich, have him check for cylinder miss first.
it could be that the wiring to or from the knock sensor has a prob. also after the knock sensor was changed was the code cleared? if it was not it may be a inactive code that stays in the computer causing the light to stay on...
Could be any number of sensors, MAF is one that comes to mind on missing. Mass Air Flow, make sure your mechanic is reading the codes and not just throwing parts at it OBDII can pinpoint the problems and parts. Computer can take up to 50 miles to reset the parameters, so it may be another 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.
