Yes. Any faulty emissions control sensor, including knock sensors, will result in an automatic fail of any emissions control test, period.

In most cases, once it is determined that a sensor is bad, the test is ended immediately, and considered failed.

How long after you clear a check engine light can you pass emissions?
It depends what caused the check engine light to come on. If there is something seriously wrong with an emission control component, simply clearing the code will not effect the results of an emissions test - the car will probably still fail. On the other hand, some codes for minor problems might not even cause the car to fail.
