Re: need help code 23?
COde 23 does mean that there is a problem with the knock sensor or its input to ECM.I would start by checking that it is plugged in/ Maybe disturbed by oil change/recent work. The check that it is tight in the block. then check continuity to to the ECM connector D Pin#3. If all is good then replace the knock sensor. Good Luck and follow up.
