Ran with no O2 Sensor
To sum it up...
I was driving, heard something banging around under car, check engine light came on. Got home, looked under car, found the O2 sensor was bouncing around cause i must have forgotten to tighten it. Ran the code and only a code for the knock sensor came up.
Can the absence of an O2 sensor cause the knock sensor code to get pulled. I figured since the O2 couldn't tell the computer the air/fuel, maybe the engine ran lean and started knocking?? Plugs looks fine as well, and compression is 220 in all 4.

Which o2 sensor fell out? The one in the manifold, or the one in the catalytic converter? If the one in the middle of the exhaust. the CC o2 sensor your fine, no damage done. Its only there to relay info to the ecu that the CC in working correctly. If the o2 sensor came out of the manifold, then you may have issues. Thats the one the engine reads to adjust fuel.

just clear the code, reinstall the sensor and run the car, I doubt the code will return. If the o2 sensor dies later down the road it will let you know.

If you weren't trying to rag on the car when this all happened I highly doubt you would have hurt the motor.
If the sensor was banging around in there the knock sensor could EASILY mistake it for engine knock. To the knock sensor tapping the engine block with a hammer sounds exactly like real knock. A dangling O2 sensor may have the exact the same effect.
But I think you're fine though....

I know it can cause the engine to knock, but just because the engine knocks mean it will throw a code for a knock sensor? Thats the only part I am not sure of.
