1997 QX4 Replacing engine knock sensor bank 1

[slshearer]

Has anyone replaced the right engine knock sensor on a 1997 Pathfinder or QX4, where is the sensor located and what is required to change it.

Thanks

I have a 99 which has the same engine and the sensor replacement should be nearly identical.

I just had mine done by my mechanic. It is located on the top of the engine block at the rear of the engine. Replacing it requires removing the entire intake manifold. I had a lot of other work done at the same time, so I don't recall exactly how much that sensor alone was, but I believe it was $175 for the part and 2.4 hours of labor.

I think some folks here have done it without remving the manifold, but I stopped by the shop when the manifold was off and saw where the sensor is and I don't know how people are able to do it.
