Sandro Seminara Posted April 29, 2008 Report Share Posted April 29, 2008 I have an OBDII tester that will tell me voltage to my O2 sensor. What should the voltage range be and under what conditions (WOT, idle, etc)RegardsSandro Link to comment Share on other sites More sharing options...
junker Posted April 29, 2008 Report Share Posted April 29, 2008 My scan tool shows it fluxuating between 0-1 volts. My rear sensor appears dead as a doorknocker... hoping for a loose connection. I don't know if these values are normal or not but at least it offers a comparison for you. Link to comment Share on other sites More sharing options...
Keaton85 Posted April 29, 2008 Report Share Posted April 29, 2008 You want it between .00 to .99 volts. The car has to be warmed up to full temp and you can do it sitting at idle. Link to comment Share on other sites More sharing options...
