VSC, Traction control, and check engine light

Asked by Nov 11, 2016 at 04:50 PM about the 2008 Toyota Sienna LE 7 Passenger

Question type: Maintenance & Repair

My wife has a 2008 Toyota Sienna. About
three years ago all of these light came on.
We looked them up in the owners manual
and it said to take vehicle to dealer. We did
not need another bill. They reset it and it
came back on two days later. This time
they said it was a sensor that needed to be
replaced and the cost was $560. A few
months later the lights came back on and
the dealer said another sensor needed to
be replaced and it would cost $4500 this
So I called a local mechanic and asked
him how much he would charge to do the
same work. He said that my problem is
caused by carbon built up and I need to
use a produce called AT-205. I had used
this produce before on other vehicles with
great success.
I put AT-205 in her van and the light stayed
off for three years.
The light came on today and I bought more
AT -205 again. My wife called me and after
about 10 minutes of driving she said the
lights went off.
I don't know what is in AT-205 but I would
say it is the one treatment produce that I
have had great luck with.
We only have one Auto parts dealer that
carries AT-205.

I don't know what an engine oil stop leak could possibly do with your ABS system but if it worked for you then great.

Hi how are you doing I have a question where can I find the AT-205
