I have a 2002 Intrepid ES and got the error codes for the O2 sensor circuit high voltage. I replaced the upstream sensors in both banks and still get the same error codes. I am assuming the fuel mixture is running rich, any suggestions on leaning the mixture? Any help/advice would be appreciated. Thanks!

thoes codes have nothing to do with that the codes are for the ckts that run them either wire issue or pcm issue. Get a volt ohm meater and test the ckts from the pcm to the o2s
