Yes. Any faulty emissions control sensor, including knock sensors, will result in an automatic fail of any emissions control test, period. It doesn't even matter if your vehicle's actual exhaust emissions are within acceptable limits. In most cases, once it is determined that a sensor is bad, the test is ended immediately, and considered failed.
