Check engine light oxygen sensor
 

Put in some music a few days ago and my idiot friend bridged the negative and positive by mistake with his wrench. It sparked and my check engine light came on. Codes p0327 p0031 p0037 came on. I cleared them and now the check engine is back on, not sure what it's saying now. Also my body control module wasn't working which I fixed by disconnecting the positive for like 5 mins. My interior lights came back on :). Anyone know anything about the oxygen sensors? The fuse looks ok.


Is it safe to drive a vehicle with non working oxygen sensors. Heard its bad at high rpm
