Would a faulty 02, front, rear etc. sensor cause a car to fail emissions testing??

I have to get an inspection sticker and I am worried that my car will fail it.

Thanks for any responses

It might fail emmisions. when a sensor fails fred puts the car in "limp home mode" meaning the last reading from the sensor is permanent until the problem is fixed. It might or might not fail emissions, it all depends on what the last reading from the sensor was.
