jhdjr Posted November 7, 2005 Share Posted November 7, 2005 The dealer's repair shop has recommended a new A1 sensor, A/F sensor dealing with the air fuel mixture. Is this really needed? or only for emissions? Is there a directory of OBD-II codes for Toyotas? Quote Link to comment Share on other sites More sharing options...

And the annoying little check engine light in your dash will go out. Quote Link to comment Share on other sites More sharing options...
