Triangle Of Doom Plus Vsc


Recommended Posts

My 2001 LS430 was showing the CEL and VSC. I bought from Rock Auto parts a new O2 sensor as per the OBD advisory, after fitting this the CEL is out and but the warning triangle is on (but NOT flashing) and so is the check VSC! Is this another oxygen sensor or something else. I am NOT going to the Stealership! (I'd change it for a Merc before I would go there!)

Any ideas would gratefully recieved! :(

There is a VSC reset procedure for my 2000 LS400 that I sometimes have to follow to turn the VSC warnings off ... don't know if it is the same for your 01 LS430 but I posted it in this thread: http://us.lexusownersclub.com/forums/index...95&hl=reset

There are a number of other issues that can cause the VSC warnings to light up including a bad battery and defective knock sensors. Life with your LS must be difficult if you absolutely can not take it to a Lexus dealer. I avoid my Lexus dealer too but I still take my car there for certain things.

This happened to me after my indie replaced the O2 sensor a couple weeks ago. It comes from some weirdness in the OBDII system; you'll have to reset the VSC system manually.


A paperclip did the job nicely.
