How do you replace crank sensor on 2003 nissan xterra 3.3L

SOURCE: nissan xterra knock sensor

It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.

You have to take the entire intake manifold off upper and lower. you will find it on the main block after you take the lower manifold off.
