Will bad oxygen sensors cause me to fail the emissions test?
Problems with the oxygen sensors are quite likely to cause emissions test problems. The car computer cannot properly adjust the air/fuel mixture to regulate the emissions.
Will a knock sensor code fail a nys inspection?
That will cause you to fail an emissions inspection. Anything which triggers the CEL will, because everything which triggers it will adversely impact the emissions system on that vehicle.
Will the knock sensor cause A car to fail a smog test?
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.

The first indication of a failed oxygen (O2) sensor are warning lights to check or service the engine.

The vehicle may also lose performance, fuel economy, and may damage other components.

What can cause a 1995 Ford Fiesta to fail on emissions?

What is wrong when the check engine light is on?
The computer has detected a problem with the emissions controls. Have the computer scanned for trouble codes. Get this fixed, as it can cause other parts to fail, as in, the catalytic converter, O2 sensor.
