Max Power Posted August 18, 2009 Share Posted August 18, 2009 91 LS400, O2 sensor was changed but the check engine light is still on. Apparently this causes the traction control to be off? Anyone have any ideas? Quote Link to comment Share on other sites More sharing options...

I just replace all my O2 sensors (4 of them) and the 2 sub-sensors are a pitty to take off Quote Link to comment Share on other sites More sharing options...
