YES. That is 1 out of several things that can cause a rough Idle.
However, keep in mind that "faulty" sensors might actually be caused by other things, such as wiring problems, computer problems, injector problems, spark plug problems, throttle body problems, etc. You need to do a proper diagnostic sequence. It is not a good idea to just start changing parts.
