follow up to strange o2 sensor data

What is your question?

after post cat o2s reading 2.125 volts i back probed the input wire going to the pcm. they showed .2-.3 knowning o2s cant report hihger then 1 volt, i replaced the pcm n thanks to autocomuterexchange.com.i got a new pcm cheap.problem fixed.forcing it lean n rich scanner data looks good.
