Blake_batonrouge Posted April 29, 2008 Share Posted April 29, 2008 I have CEL code 28 - Main oxygen sensor signal (on right bank) Which side is the right bank? Is it driver or passenger side? Also how do you diffrentate between the two? From sitting in the drivers seat or standing outside looking into the engine? Quote Link to comment Share on other sites More sharing options...

Blake_batonrouge Posted April 29, 2008 Author Share Posted April 29, 2008 Also is the main sensor before or after the CAT? I am trying to get the direct plug in from Autozone and it is offering a before and after cat sensor. Quote Link to comment Share on other sites More sharing options...
