I just got a code on my 2005 Nissan Altima 2.5 that said my crankshaft&camshaft sensor's were bad. I replaced both of them and the car ran grate for two days now its doing the same thing as before. IT runs good but there is a odd sound coming from the front passenger side of the motor. Now I get a p0420 saying the O2 sensor is bad. I was wondering if the sensor could cause this noise. Thank you for any help you can give me

Do you
have the same problem?

Here is the chart that nissan puts out. Your converter loses temp is a 420 code. Your cam/crank sensor could be a dirty battery cables or the sensors may have gone out of phase. Also check for poor connections poor grounds or shorted wires.
