Take the upper engine cover off, climb over the engine and reach behind the engine, remove the 10mm head bolt from the sensor and pull it out of the cylinder head, pull the sensor up by the harness, replace the sensor and reverse to install. I would recommend you do it on a cold engine.
Thanks ...

You'll have to ask an engineer why a computer wouldn't pick up a bad sensor; I can only tell you what I've seen. As I said, I try not to recommend replacing parts unless they can be proven as defective. The cam and cranks sensors have a similar design and have had a history of failures since the ...

As I already posted, there is a cam sensor on the back of each head, and one of them "could" be the problem. I really don't like suggesting parts replacement without doing the diagnostics to confirm the parts are bad, as it can get expensive. There are downloadable service manuals on the web for ...

2010 Pathfinder S Cranks but Will Not Start when Cold
I have a 2010 Pathfinder S 4L V6 engine. Now that it is cold out, my Pathfinder will not start. I had some trouble starting it the last month in the morning when it was cold, but then when it warmed up it seems to start up okay. I replaced the battery and cleaned the connectors so that is not the ...
