Knock sensor ?

Can any one tell me where the knock sensor on a 2000 frontier with the V6 engine is located. I have a check engine light and get a P0325 code knock sensor. I cleared it with my scanner but it came back went I started the truck. Thanks in advance.

If it is a 3.0 it is located under the intake manifold. I seem to be having a similar problem, so please post if you find a solution.

The Frontier is a 3.3 liter I think. Its my neighbors. I called Napa the sensor is $85 and $130 at the dealer. If its under the intake that is going to be a real pain to get to.

Awefully early for a knock sensor failure... has the truck over heated? Might also check the electrical connections for corrosion... a common problem on the older Q45s, but they seem to be overheating related or much later in the life of the car...

The 3.3L V-6 KS is still located under the intake manifold. You need to remove the manifold in order to access it. PITA, yes, but DIY-able.

Thanks to all who responded. The neighbor had his truck in the shop and they said they replaced an injector under the intake manifold. Now the puzzle is coming together. I wonder if the prior mechanic broke the plug or a wire etc.

I'm takikng my QX-4 to the Nissan dealer tomorrow for the same problem. I'm hoping they don't take me to the bank!

The sensor is under the upper intake manifold and it has to come off in order to get to it. I also have a 2000 4X4 with and error code indicating there is a knock sensor issue.?
