2001 Infiniti I30 Knock Sensor

Is there a way to change this sensor without taking the manifold off? I've seen pictures of the sensor on other years, but I can't even see the thing on my car, too much stuff in the way.

There might be. It involves tiny hands, a varied combination of swivel joint socket adapters and a good flashlight... and a lot of patience.
Good luck!

If you can unplug it from the harness you might a multimeter to
see if it has the correct resistance and if you are getting power
to it before removing it
