02 Circuit

[Kieran A. Lavin]

Have you actually pulled the code off the ecu though?  See what that trouble code is and get your hands on an FSM and go through the troubleshooting.  Sounds like there might be a short somewhere?  FSM is pretty good at helping you pinpoint (sort of) where the short might be coming from.  I went through it on my wife's 02 Maxima and spent a week or so looking for various codes when it turned out to be the damned ECU not screwed in tight from troubleshooting OTHER codes previously!

Hi all,

Anyone know what an o2 circuit is?  My father-in-law's 98 Maxima is giving this off as an error via my OBD reader.  It previously said o2 sensor which I replaced, now this.  Any help would be much appreciated.
