johnl848 Posted January 26, 2010 Share Posted January 26, 2010 I think it's the O2 sensor,but not sure.The voltages are Black-3v steady, Yellow-2.5v steady,Grey-.3v steady,White-7.39 to 7.41v,Red-2.3 to 2.9v.The rear O2 sensor seams to be toggling great between .2 to.8.Can someone point me in a direction?I have to go through emissions Link to comment Share on other sites More sharing options...
nipper Posted January 26, 2010 Share Posted January 26, 2010 How many miles. Do a search on Oxygen Sensor, but odds are thats what it is. nipper Link to comment Share on other sites More sharing options...
johnl848 Posted January 28, 2010 Author Share Posted January 28, 2010 It has 130,000mi. Was wondering if those voltages were normal.I've only delt with o2 sensers that vary 1v.Sorry for the delay in my response,but I just lost a dear friend at the tender age of 48.I didn't want to lose the help to get this problem solved so I can clear this with emissions.Thanks!
