I believe the knock sensor is under the intake manifold requiring it's removal. I have not been able to verify this yet.

If that's the case, be prepared to get giggy with this engine. It's not an easy, logical design, so you might want to take care of some things while you're in deep. For example, the manual calls for the timimg belt to be replaced at 120,000 miles (if memory serves) so you may as well tackle that also.

Xterra Haynes manuals are few and far between. I strongly suggest acquiring either the Haynes or a FSM before getting giggy with this engine.


Eureka! We sucessfully did it another way and saved about $500. (est. from a mechanic to replace with me buying the part.) Go through the front of the engine. We were replacing the time belt etc. anyway.... I have photos showing the 'impossible' too.

We were told that the knock sensor wasnt that big a deal that the truck would still be ok if that was not changed. What we did change was the crankshaft position sensor that was bad. But we are still having the same problem as before when the engine gets hot it wants to cuts out. Would the knock cause that sort of problem?

it is underneath the lower intake in the middle of the "valley" on V6 models. between the cylinder heads on the block. pretty big job. the knock sensor WILL NOT turn the check engine light on. it will store a code but NOT turn the light on. (i am a Nissan tech, trust me) it will effect the timing and fuel strategy though.
