Question
Nissan Xterra 2002,, (po328),, where is the knock sensor located ?

Answer
Hi Stephen -

The knock sensor is usually located on the intake manifold. It usually has a blue terminal and a hex shape for ease of removal. Knock sensor monitor pinging (when the spark plugs fire too early before TDC and slams the piston against the cylinder walls).

Hope this helps -
