all i knowit is located under the intake manifold in the center (v6) and on the side of the engen block on the 4 cylinder

it's a lot of work, but the sensor is located under the intake manifold. It requires removing the upper half of the intake manifold, the injector rack, the the bottom half of the intake manifold. Remember to release the fuel pressure, drain the coolant and keep track of all your parts. While you have that off, It's best to go ahead and change the plugs.

Ok heres the 411 on it. its a useless sensor its throwing a code P0325. yes its a pain in the *** to replace, but its not doing anything to your engine as far as fuel economy or timing. So in short just let it be. my 2000 frontier has the same problem.

Nissan/Toyota Tech

It allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop.

A knock sensor assures that you're getting as much power and What_does_a_knock_sensor_doas is possible from your engine. yeah i would not listen to that last guy he knows nothing at all

The knock sensor for most Nissan V6 engines is located directly under the intake manifold. So to replace it, you have to remove the intake manifold. Good Luck.

The knock sensor on Nissan 300ZX non-turbo from 1990 thru 1996 is located below the lower intake manifold on the rear of the engine block. To replace the knock sensor the upper and lower intake manifolds need to be removed. It is always best to replace the knock sensor with a new one considering its major dissasembly.

Trouble code P0328 means: Knock sensor #1 circuit high input (Bank 1 or single sensor)

The actual cost of a new knock sensor is in the range of $150-200, depending on the brand. For a labor estimate, best bet is to call a local auto repair shop for a quote.

Disconnect the wire from the sensor, use an open ended adjustable wrench to unscrew it. take a new sensor and screw it in. on a different model (if not a standard sensor) there is a nut and bolt holding it in, use the steps above to replace it
