2005 Toyota 4Runner vsc/trac light on


Topic starter

Thank you for your channel and all the good advice you give!  I am a great fan of you!


I own a 2005 4runner 6 cyl automatic with over 200k miles.  The check engine light goes on and the vsc / trac light goes on.  I notice the vehicle behaves funny when this happens.  I just had the transmission rebuilt and the vehicle rides like a dream (I love it) but this vsc / trac light is driving me crazy.  When I hook up the scanner it usualy tells me codes like po137 (I replaced all the O2 sensors with Denso (original type) and the code come back.  Any Advice?   Thanks!
